HTML Computercode

Computer Code

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

HTML <kbd> For Keyboard Input

The HTML <kbd> element represents user input, like keyboard input or voice commands.

Text surrounded by <kbd> tags is typically displayed in the browser's default monospace font:


<p>Save the document by pressing <kbd>Ctrl + S</kbd></p>

Save the document by pressing Ctrl + S

HTML <samp> For Program Output

The HTML <samp> element represents output from a program or computing system.

Text surrounded by <samp> tags is typically displayed in the browser's default monospace font.

Example

<p>If you input wrong value, the program will return <samp>Error!</samp></p>

Result:

If you input wrong value, the program will return Error!

HTML <code> For Computer Code

The HTML <code> element defines a fragment of computer code.

Text surrounded by <code> tags is typically displayed in the browser's default monospace font:

Example:

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

Result:

x = 5; y = 6; z = x + y;

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:

Example:

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

Result

x = 5;
y = 6;
z = x + y;

HTML <var> For Variables

The HTML <var> element defines a variable.

The variable could be a variable in a mathematical expression or a variable in programming context:



Example



Einstein wrote: <var>E</var> = <var>mc</var><sup>2</sup>.

Result:
Einstein wrote: E = mc2.
