HTML Computer Code Elements

HTML contains several elements for defining user input and computer code.

HTML Computer Code Elements

Tag	Description
`<code>`	Defines programming code
`<kbd>`	Defines keyboard input
`<samp>`	Defines computer output
`<var>`	Defines a variable
`<pre>`	Defines preformatted text

HTML `<code>` For Keyboard Input

The HTML <code> element is used to define a piece of computer code. The content inside is displayed in the browser's default monospace font.

Example:

<!DOCTYPE html>  
<html>  
	<body>  
		<h2>Computer Code</h2>  
		<p>This is a programming code:</p>  
		<code>  
			x = 5;  
			y = 6;  
			z = x + y;  
		</code>  
	</body>  
</html>

Output:

Notice that the <code> element does not preserve extra whitespace and line-breaks.

To fix this, you can put the <code> element inside a <pre> element:

<pre>
<code>  
	x = 5;  
	y = 6;  
	z = x + y;  
</code>  
</pre>

HTML `<kbd>` For Keyboard Input

The HTML <kbd> element is used to define keyboard input. The content inside is displayed in the browser's default monospace font.

Example:

<!DOCTYPE html>  
<html>  
	<body>  
		<h2>The kbd Element</h2>  
		<kbd>This is how  content written within kbd element looks like.</kbd></p>  
	</body>  
</html>  

Output:

HTML `<samp>` For Program Output

The HTML <samp> element is used to define sample output from a computer program. The content inside is displayed in the browser's default monospace font.

Example:

<!DOCTYPE html>  
<html>  
	<body>  
		<h2>The samp Element</h2>  
		<samp>This is how the content within samp element looks like. </samp>  
	</body>  
</html>  

Output:

HTML `<var>` For Variables

The HTML <var> element is used to define a variable in programming or in a mathematical expression. The content inside is typically displayed in italic.

Example:

<!DOCTYPE html>  
<html>  
	<body>  
		<h2>The var Element</h2>  
		<var>E</var> = <var>mc</var><sup>2</sup>
	</body>  
</html>  

Output:

HTML `<pre>` element

The <pre> element defines preformatted text, which displays the content within it in a fixed-width font. It keeps the content into its original format and ignores all formatting.

<!DOCTYPE html>  
<html>  
	<body>  
		<h3>Example of pre tag</h3>  
		<pre>  
This is content written   
within pre tag, and  pre tag will ignore all   
spaces,     break lines, and will display the content   
as in original format.   
		</pre>  
	</body>  
</html>
