HTML <code> For Computer Code
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
Define some text as computer code in a document:
<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 is used
to define a variable in programming or in a mathematical expression. The
content inside is typically displayed in italic.
Example
Define some text as variables in a document:
<p>The area of a triangle is: 1/2 x <var>b</var> x <var>h</var>, where <var>b</var>
is the base, and <var>h</var> is the vertical height.</p>
Result:
The area of a triangle is: 1/2 x b x h, where b is the base, and h is the vertical height.
