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.
