The LCD Panel is a thin panel that takes an entire block face and can display a variety of messages and textures that can be displayed constantly or triggered by the Programmable Block, Sensor, Timer Block, or any other block capable of triggering.

The "Color" sliders allow setting the text colour using RGB slider and "Backgr." allows setting background fill colours (default black). If using a transparent LCD then the text will be against transparency unless fill colour is added.

"Loaded Textures" has a list of the available default and modded (where applicable) images available for display on the screen. Select the desired image and select "Add to selection". The selected image will then show in the second "Selected textures" panel.

When multiple images are applied they can be set to cycle between with the duration between images being set by the "Image change interval" slider. To remove an image from display select it in the second panel and select "Remove selected".

The "Preserve aspect ratio" checkbox can be used to prevent the image being stretched if it does not fit the screen properly such as when using a wide LCD.

To set the LCD to display a script, choose "Script" from the dropdown. Choosing Script allows the display of information such as weather, artificial horizon for vehicles, Energy and Hydrogen level etc.

The panel"s title and text can be made public, private, or a combination of both. Textures applied can be selected from a list or custom textures can be selected. Textures can be set to rotate on a timer, changing from one to the next. GPS coordinates shown in the GPS format in the text panel will appear in the GPS and can be activated (=shown on HUD).

The LCD Panel could be accessed with the programmable block as IMyTextPanel. It could work in ´Texture Mode´ in which the selected textures are shown or the ´Text Mode´ in which the text is shown. The following methods are available:

After many requests, we have decided to release our internal Replay Tool that we use to create our trailers. It allows you to record the movement and actions of multiple characters in the same world. You can use your video recording software of choice to capture these moments for cinematic purposes! It’s also super useful for epic screenshot creation. The tool allows you to be the director of your own Space Engineers film where you can carefully position and time different engineers with their own specific roles. We are extremely excited to see what the community will create with this!

Important: because it’s an internal tool, it has a very basic user interface and required advanced users to be used. We believe this is OK, because most video creators who would want to use it to create epic cinematic Space Engineers videos are advanced users.

There are now Steam trading cards to collect for Space Engineers! Collect a full set of cards to earn items that help you customize your Steam profile including backgrounds and badges.

There are fourteen new decorative blocks for people who want to buy them and support the development of Space Engineers, which are available on the Space Engineers Steam Store page. Within the package you will get following new blocks:

Beds can preserve characters’ inventory and toolbar while they"re offline and keeps them alive as long as there is oxygen available. Is considered to be the same as the Cryo Chamber Block, except oxygen is used from the environment. Space Engineers don’t work from nine to five, they work whenever they’re needed: day or night, during peace and war. But when it’s time to call it a day, every engineer looks forward to resting in these beds.

Kitchens are purely decorative. The kitchens in Space Engineers come well-equipped and include stunning visual details. Space Engineers overcome challenges everyday when they’re working on new planets or among the stars.

Planters are purely decorative, but they make outer space a bit warmer by housing life in a special glass container. Build your own garden on the space station. Planters not only help to liven up spaces, but the flora housed inside these capsules also remind many engineers of the homes they’ve left behind in order to explore the universe.

Couchescan be used as seats, so take your time to relax and take a break. You don’t need to always run, fly or work, you can enjoy your cozy room and enjoy the view. The last thing anyone would ever call a Space Engineer is ‘couch potato’, but who wouldn’t like to relax after a hard day’s work on this comfy furniture?

Armory and Armory Lockers can be used to decorate interiors and store weapons, ammunition, tools and bottles; both are small storages (400L), where you can keep your equipment. Space Engineers use lockers in order to ensure that keepsakes from home, toiletries and other items are kept safe.

Toiletscan be used as a seat. The latest and greatest interstellar lavatory technology has made many earth dwellers jealous of the facilities enjoyed by Space Engineers.

Toilet Seat that can be used as a seat and is fit for the creator of the legendary Red Ship; most engineers don’t want to get up after ‘taking care of business’.

Industrial Cockpits are used to control your ships. This industrial cockpit in both small and large grid versions will make your creations look much better. Offering unmatched visibility, the industrial cockpit enables engineers to experience stunning vistas while traversing landscapes and space.

Console blocks project blueprints for downscaled ships and stations, as well as display pictograms or customizable text. They are fantastic functional LCD panels where you can project your creations and show them to your friends. The sleek and crystal clear picture offered by this console allows Space Engineers to display designs and other important information.

Keen Software House needs to stay profitable in order to continue development and support of Space Engineers, and to take risks, to invest into experiments that may not pay off in the short term, and to develop innovative concepts.

A:Actually, even this update isn’t paid. The major part of this update (LCD screens, Replay Tool, new music tracks, smaller improvements) is free for everyone. Only the smaller and not mandatory part is paid - Decorative Pack, which you can purchase here.

A: To support future development of Space Engineers and other leading-edge projects we plan to work on at Keen Software House. Players kept asking us for something they could buy to support the development of Space Engineers, and the Decorative Pack is a great option for them.

A: Right after Space Engineers left early access and all hot issues were resolved. Most of the work was done by the Art team, the rest of the developers is working on other long-term updates.

A: We want more people to play Space Engineers, which means we must lower the barrier of entry. When the Space Engineers community grows, everyone benefits from this - more content on Workshop, more mods, more new ideas, more people to play with. This means that all non-mandatory features should be optional, so only those who really want them can pay for them. That’s why we decreased the price of Space Engineers, and made the Decorative Pack an optional purchase.

The various LCD Panel blocks are a great way to add a human touch to a ship or base by displaying useful images or text. For LCD configuration and usage, see LCD Surface Options.

Note: Some functional blocks, such as Cockpits, Programmable Blocks, Custom Turret Controllers, and Button Panels, have customizable LCD surfaces built in that work the same way as LCD Panel blocks, which are also discussed in detail under LCD Surface Options.

LCD Panels need to be built on a powered grid to work. Without power, they display an "Offline" text. While powered without having a text, image, or script set up, they display "Online".

LCD Panel blocks come in a variety of sizes from tiny to huge (see list below) and are available for large and small grid sizes. Note that LCD Panel blocks all have connections on their backs, and very few also on a second side.

All LCD Panels and LCD surfaces work with the same principle: They are capable of displaying dynamic scripts, or few inbuilt static images accompanied by editable text. Access the ship"s Control Panel Screen to configure LCD Panels or LCD surfaces; or face the LCD Panel block and press "K".

A Text Panel, despite its name, can also display images. On large grid, it is rectangular and does not fully cover the side of a 1x1x1 block. On small grid it is 1x1x1, the smallest possible LCD block in game.

On large grid, you choose the Text Panel when you need something that has rectangular dimensions that make it look like a wall-mounted TV or computer screen. If you want to display images, this one works best with the built-in posters whose names end in "H" or "V" (for horizontal or vertical rotation). On Small grid, you place these tiny display surfaces so you can see them well while seated in a cockpit or control seat, to create a custom display array of flight and status information around you.

Corner LCDs are much smaller display panels that typically hold a few lines of text. They don"t cover the block you place them on and are best suited as signage for doors, passages, or containers. They are less suitable for displaying images, even though it"s possible. If you enable the "Keep aspect ratio" option, the image will take up less than a third of the available space.

These huge Sci-Fi LCD Panels come in sizes of 5x5, 5x3, and 3x3 blocks, and can be built on large grids only. These panels are only available to build if you purchase the "Sparks of the Future" pack DLC.

They work the same as all other LCD Panels, the only difference is that they are very large. In the scenario that comes with the free "Sparks of the Future" update, they are used prominently as advertisement boards on an asteroid station.

This LCD panel can be built on large and small grids. The transparent LCD is basically a 1x1x1 framed window that displays images and text. It is part of the paid "Decorative Blocks Pack #2" DLC.

What is special about them is that if you set the background color to black, this panel becomes a transparent window with a built-in display. In contrast to other LCD Panels it has no solid backside, which makes it ideal to construct transparent cockpit HUDs, or simply as cosmetic decoration.

While configuring an LCD Panel, the GUI covers up the display in-world and you can"t see how the text or images comes out. In the UI Options, you can lower the UI Background opacity to be translucent, so you can watch what you are doing more easily.

VST was designed to allow users to design game scenarios for Space Engineers without needing previous coding experience. Mod developers can utilize this tool to create scripted gameplay events, play cutscenes, or modify game values at runtime.​

World Outliner: Panel in VST which interfaces with any World currently running in an instance of Space Engineers, allowing designers to view, create, edit, and delete Waypoints outside of IST.

This pane lists all available scripts in the open scenario. From here you can open scripts to edit, create new scripts, and drag Common scripts onto open Objective graphs.

Scripts are organized by type (See Script Types section below) and listed alphabetically by file name. ​New scripts can be created through this pane by right clicking the parent directory you want to create or import a script under.When creating a new Mission script, VST will automatically create an accompanying State Machine script in addition to the required World directory and files. Only one State Machine can be run per Mission, so there is no need to create new State Machines by themselves.

Click on any item in the tree to select it. At the bottom of the pane there is a contextual description box, with a brief summary of the selected node’s functionality.

This pane interfaces with Space Engineers, allowing designers to view, create, edit, and delete Waypoints inside an open World. The World does not need to be connected to the open Scenario however, and the Outliner will connect to any running game World. If no World is currently running, the Outliner will be greyed out and inactive.

​The top buttons are useful for quick actions, such as adding a new Waypoint or Saving. When a new Waypoint is added via the New Waypoint button, it is created at the camera’s current position in the world. In IST the new Waypoint can be moved in 3d space with its gizmo, or have its position values set manually.

The Script Editor is where the majority of work is done in VST, displaying the Graphs for any Mission, Objective, or Common script you open. State Machine graphs function slightly differently, and will be discussed in the next section. All open scripts are listed as tabs at the top with their names, and can be reorganized as individual panes in your workspace.

Gameplay scripting is designed by creating and connecting Nodes in a script’s Graph in this pane. Nodes are called in sequence going from left to right along the white Sequence Line, starting at an orange Event node.

The State Machine graph can be opened by double-clicking a State Machine in the Scenario Explorer pane. This Graph works similarly to the Script Editor, but only uses a small number of node types unique to State Machines:

State Machines control when and in what order Objective scripts are run, allowing for some code to only be run at specific times. While code in a Mission script is accessible at any time during the Mission, code inside Objective scripts are only accessible when a State Machine is running the Objective.

A State Machine can be started from a Mission script by calling the StartStateMachine node. Using a State Machine to run Objective scripts allows you to better organize and optimize your scripts, but it is not required.

States can be connected through transitions, which determines the order in which the states will be run. Each transition has a name given when it is made, which must be referenced when completing an Objective script.

When a State Machine is started, it begins by running the state denoted in the World’s Sandbox.sbc data file under the VisualScriptManagerSessionComponent section. If this node is deleted and no longer exists on the Graph, Space Engineers will select a different node with no incoming connections as the initial state to run.

To progress the State Machine’s Cursor to the next state, the Objective script needs to call a Complete node, and specify the name of the transition to progress down. This stop the current Objective, and begins running the Objective associated with the connected State in the named transition.

If this is your first time running VST, you’ll be prompted to “Select Content folder of the game.” Navigate to the Steam installation folder on your computer, and select …\Steam\steamapps\common\SpaceEngineers\Content\

​If Space Engineers is already running, you can open your scenario by selecting New Game on the Main Menu, then scrolling down the list of official scenarios to view your Local scenarios. These local scenario directories can be found in your AppData folder for Space Engineers, in the \AppData\Roaming\SpaceEngineers\Mods\ folder.

You can open Space Engineers and directly load directly into your scenario by clicking “Run” on the Ribbon bar. The “Run Scenario” button can be used to also save all changes directly to the scenario folder in \Mods\, rather than to your \Saves\ folder, making it easier to edit and save changes to your World. This method requires that Space Engineers not have any instances already running on your computer.

​When the game has finished loading and you gain control of the character in the world, the GameStarted Event in the Mission script will be called. If you left the StartStateMachine node connected to this event, the State Machine will also start running its first State node’s Objective script, and the code prints a Hello World message to the Chat window.

​Regardless of what kind of scenario you’re making, all scripting in VST begins with Event nodes. These nodes fire when their associated event takes place in the game. GameStarted, for instance, fires immediately when the scenario begins for the first time, and any connected nodes will be called when that happens.

The easiest Event node to begin scripting with is ButtonPressedTerminalName, which fires any time a button panel is activated in the game. This event is great for causing scripts to run at specific times, since the player has direct control over when it fires.

It can sometimes be difficult to know what specific code is running in your script, since many nodes do not produce visible changes in the level. An easy way to debug your code is to use the SendChatMessage node to print messages to the in-game Chat window. Printing messages this way can help you determine when an Event is firing, as well as enables you to print variable values through the message field.

​Next, click Run Scenario on the Ribbon bar to launch Space Engineers and load directly into this scenario with saving enabled. When you gain control of the character, create a button panel block, and assign any block action to the first slot.

In the previous section you created a simple button event, connected to a chat message node. Since there are no logical checks, and the Event node is on the Mission script’s Graph, this message will be printed to the Chat window when any button is pressed at any time during the Mission. You can easily constrain this code to only one specific button by checking some of the event’s parameters.

​First, you’ll need to have a Branch node connected along the Sequence Line between the Event and the SendChatMessage nodes. Branch nodes check a boolean value, much like a traditional If / Else statement, and only executes one of its two output connections. We’ll use this Branch node to check the name of the button panel block provided by the Event node, so connect the True output to the SendChatMessage node.

StringContains is a great way to analyze strings such as Entity names, and determine if a sample string can be identified within the value string. For our event, we’ll want to check the button panel’s terminal name, and only print the message if it contains a specific string. Double click into the “contains” field on the StringContains node, type “test”, then click “OK” to confirm. This will cause the StringContains to evaluate “true” for its output boolean value only when the Event’s output name string contains the word “test”.

Open the panel’s terminal, and click the Name field to edit the block’s name. Adding the test string to the name will now allow the chat message to print. Keep in mind that StringContains is case sensitive, so adding “Test” or “TEST” to the terminal name will evaluate to false in our logic.

Next, we’ll learn how to start and progress through a series of Objective scripts via the State Machine. Don’t forget to save your changes to retain the updated terminal name!

In the previous section, you learned how to target a specific button by name, but it is still accessible at any time during the Mission. Moving the nodes into an Objective script allows the code to only be run during specific States.

First, click and drag in an open space on the graph to create a selection box. Drag the box around the Event, Branch, and SendChatMessage nodes, and release to select all the newly created nodes. Press Ctrl+C on your keyboard to copy these nodes to your clipboard.

Next, open the Mission01_Start Objective script by double clicking it in the Scenario Explorer pane. Press Ctrl+V on your keyboard to paste the nodes into the Objective script. Now that you have successfully pasted the nodes, return to the Mission script and delete the selected nodes there. The button can now only print your message when the Start state is active.

By default, new scenarios are set up with code to start the State Machine on GameStarted, and print a Hello World message before moving to the Part state. Go back to the _Start Objective script, and move the Complete node from the Init event to the end of your ButtonPressed event. This way, the State Machine will not progress past this state until the test button is pressed.

Using the State Machine and Objective scripts in this way can allow you to design unique scripted events, and control when they are called during your scenario. It also helps keep the scripts stay organized and optimized, since large amounts of nodes can slow down viewing a script in VST.

In order to set your scenario’s description, you’ll need to open your scenario’s .SCF data file in a text editor program, such as Notepad. You can find this data file in the \Mods\ScenarioName\Scenarios\ScenarioName\ folder, and it will be named the same as your scenario’s name. Between the and tags, you can write out a custom description to display to players on the Scenario selection screen.

After you’ve set up these cosmetic extras, your scenario is ready to publish. On the Main Menu for Space Engineers, click New Game to view the Scenario selection screen. Here you can review your changes to the thumbnail and description, and click Publish at the bottom when you’re ready to share.

The In-game Scripting Tool (IST), also known as the “Scripting Tools” screen, is used to create and modify entities in a World. IST is ideal for placing Waypoints, creating Trigger volumes, and naming grids or blocks for referencing with VST.

These are the main scripts for a Scenario, and are set up in sequence on the Scenario Editor tab. A Scenario can have multiple Missions, but only one Mission can be run at a time. Each mission requires its own World, which is generated automatically when creating a new Scenario or Mission script.

These scripts begin running when the game is loaded, based on their order in the Scenario Editor tab, and will run until the SessionClose node is executed. Events and logic in this script can run at any point while playing this Mission.

To create a new Mission in your Scenario, right click in the Scenario Explorer and select Add New Mission. You will be prompted to input a Name, select a World and Loading Image to use as templates, and input an optional Loading Text. After clicking Create VST will generate a new Mission script, State Machine, and all required World files.

​These scripts control the flow of individual Objective scripts in sequence during a Mission. The State Machine can be started from any script with the StartStateMachine node. Each State in the State Machine represents a specific Objective script, which are connected through Transition connections. States without input Transitions will be treated as starting nodes, and run when the State Machine is started.

All Transitions have an identifying name, which is input when connecting two States and creating the Transition. The Cursor moves along Transitions, activating the Objective scripts associated with its current State. To move the Cursor from one State to the next during play, the associated Objective script must execute the Complete node and specify the Transition name.

Specific scripts that are only run at certain times during the mission, and controlled by the State Machine. Code in these scripts do not run if a State Machine Cursor is not active on its State. When a Complete node is executed in an Objective script, the script is stopped and the Cursor moves to the next State in the State Machine.

Objective scripts are useful for segmenting your code, and only running what is needed to at a given time. This can keep your Scenario organized, making it easier to navigate and debug, as well as maintain steady run-time performance.

This script type is used for generalized, modular logic which can be repeated multiple in places. Common scripts can be placed in Mission or Objective scripts as nodes by clicking and dragging them onto a graph from the Scenario Explorer pane.

Two node types are specific to Common scripts: Input and Output, which mark the beginning and end of the Common script respectively. Both of these nodes can have parameters added to them, allowing for variables to be passed in or returned out.

Everything you will ever need to know about your ship and station displayed in real time on LCD panels in any vanilla games. modded games and servers! Now with cockpit panels support!

Thank all of you for making amazing creations with this script, using it and helping each other use it. Its 2022 - it"s been 7 years already since I uploaded first Configurable Automatic LCDs script and you are all still using it (in "a bit" upgraded form). Its just amazing :)

Every captain wants to have displays that show some useful info. Make your bridge display damaged blocks in engineering, engine room, etc. Make big screen by joining multiple Wide LCDs! Show power output, batteries status, laser antenna connections and much more. Make your docking bay display which landing gears are occupied. Make screens for docking fighers when landing gear is ready to dock so they can nicely see it from cockpit! Make one LCD per container to see its contents.. and much more!

HOW TO UPDATE?This script is not a mod so it does not update by itself. You need to load new version of script to your programmable block to overwrite the old one. You do that in exactly the same way as when you first loaded the script into programmable block.

Open your programmable block, click Edit, click Browse Workshop, select Automatic LCDs 2, click OK, Check code, Remember & Exit. Done. Your script is now updated.

!! PLEASE READ THIS !!I"m really happy that this script became so popular and that so many people like it, but many people means many questions and I rather enjoy other things than saying the same things all over again to people. So I wrote the guide where I"ve put everything about every command, tried to answer all questions that people had in comments and I keep it updated. I"m responding to many comments that are stated in the guide. Please read the guide.

I understand that this script got quite a lot of features and it can be hard to crunch whole guide. Unfortunately I can"t teach everyone how to use it via chat. It took me several hundreds of hours to put this all together so please take your time to read the guide and follow the troubleshooting section if something doesn"t work.

If you have problem with some command then read the guide section for that command and make sure you use it correctly. Try to use it on separate LCD by itself so it"s easier for you to see the issue and definitely try some examples!

The game even provides a creative mode where you can basically enable unlimited resources and instant crafting, essentially letting you do anything you can imagine. It’s The Sims, but for outer space.

While there are mods that add functionality and data displays to aid your space exploration, there are lots of useful scripts that let you automate certain commands as well.

He actually takes inspiration from real-time strategy games to give you easier control of units in Space Engineers, with Fleet Command MKII targeted specifically at controlling ship fleets.

Other than the Death Star gun and Star Trek cockpit, the modding community has come up with loads of new parts for you to use to make your Space Engineers ships even better.

These last two aren’t as big compared to other entries, but are more like bonus mods that showcase the endless possibilities offered in Space Engineers.

The behavior of GameObjectsThe fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more. A GameObject’s functionality is defined by the Components attached to it. More info is controlled by the ComponentsA functional part of a GameObject. A GameObject can contain any number of components. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour. More info that are attached to them. Although Unity’s built-in Components can be very versatile, you will soon find you need to go beyond what they can provide to implement your own gameplay features. Unity allows you to create your own Components using scripts. These allow you to trigger game events, modify Component properties over time and respond to user input in any way you like.

Unlike most other assets, scripts are usually created within Unity directly. You can create a new script from the Create menu at the top left of the Project panel or by selecting Assets > Create > C# Script from the main menu.

The new script will be created in whichever folder you have selected in the Project panel. The new script file’s name will be selected, prompting you to enter a new name.

It is a good idea to enter the name of the new script at this point rather than editing it later. The name that you enter will be used to create the initial text inside the file, as described below.

When you double-click a script Asset in Unity, it will be opened in a text editor. By default, Unity will use Visual Studio, but you can select any editor you like from the External Tools panel in Unity’s preferences (go to Unity > Preferences).

A script makes its connection with the internal workings of Unity by implementing a class which derives from the built-in class called MonoBehaviour. You can think of a class as a kind of blueprint for creating a new Component type that can be attached to GameObjects. Each time you attach a script component to a GameObject, it creates a new instance of the object defined by the blueprint. The name of the class is taken from the name you supplied when the file was created. The class name and file name must be the same to enable the script component to be attached to a GameObject.

Note to experienced programmers: you may be surprised that initialization of an object is not done using a constructor function. This is because the construction of objects is handled by the editor and does not take place at the start of gameplay as you might expect. If you attempt to define a constructor for a script component, it will interfere with the normal operation of Unity and can cause major problems with the project.

As noted above, a script only defines a blueprint for a Component and so none of its code will be activated until an instance of the script is attached to a GameObject. You can attach a script by dragging the script asset to a GameObject in the hierarchy panel or to the inspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info of the GameObject that is currently selected. There is also a Scripts submenu on the Component menu which will contain all the scripts available in the project, including those you have created yourself. The script instance looks much like any other Component in the Inspector:

Once attached, the script will start working when you press Play and run the game. You can check this by adding the following code in the Start function:-

The HyperText Markup Language or HTML is the standard markup language for documents designed to be displayed in a web browser. It can be assisted by technologies such as Cascading Style Sheets (CSS) and scripting languages such as JavaScript.

HTML can embed programs written in a scripting language such as JavaScript, which affects the behavior and content of web pages. The inclusion of CSS defines the look and layout of content. The World Wide Web Consortium (W3C), former maintainer of the HTML and current maintainer of the CSS standards, has encouraged the use of CSS over explicit presentational HTML since 1997.HTML5, is used to display video and audio, primarily using the element, in collaboration with javascript.

The first publicly available description of HTML was a document called "HTML Tags", first mentioned on the Internet by Tim Berners-Lee in late 1991.SGMLguid, an in-house Standard Generalized Markup Language (SGML)-based documentation format at CERN. Eleven of these elements still exist in HTML 4.

ISO/IEC 15445:2000ISO HTML", based on HTML 4.01 Strict) was published as an ISO/IEC international standard. In the ISO this standard falls in the domain of the ISO/IEC JTC 1/SC 34 (ISO/IEC Joint Technical Committee 1, Subcommittee 34 – Document description and processing languages).

The id attribute provides a document-wide unique identifier for an element. This is used to identify the element so that stylesheets can alter its presentational properties, and scripts may alter, animate or delete its contents or presentation. Appended to the URL of the page, it provides a globally unique identifier for the element, typically a sub-section of the page. For example, the ID "Attributes" in https://en.wikipedia.org/wiki/HTML#Attributes.

HTML defines several data types for element content, such as script data and stylesheet data, and a plethora of types for attribute values, including IDs, names, URIs, numbers, units of length, languages, media descriptors, colors, character encodings, dates and times, and so on. All of these data types are specializations of character data.

Aside from the different opening declarations for a document, the differences between an HTML 4.01 and XHTML 1.0 document—in each of the corresponding DTDs—are largely syntactic. The underlying syntax of HTML allows many shortcuts that XHTML does not, such as elements with optional opening or closing tags, and even empty elements which must not have an end tag. By contrast, XHTML requires all elements to have an opening tag and a closing tag. XHTML, however, also introduces a new shortcut: an XHTML tag may be opened and closed within the same tag, by including a slash before the end of the tag like this:
. The introduction of this shorthand, which is not used in the SGML declaration for HTML 4.01, may confuse earlier software unfamiliar with this new convention. A fix for this is to include a space before closing the tag, as such:
.
