HTML
Marking up computer code
Block with and
Example
If the formatting (white space, new lines, indentation) of the code matters, use the pre element in combination with the code element:
<pre>
<code>
x = 42
if x == 42:
print "x is … … 42"
</code>
</pre>
You still have to escape characters with special meaning in HTML (like < with <), so for displaying a block of HTML code (<p>This is a paragraph.</p>), it could look like this:
<pre>
<code>
<p>This is a paragraph.</p>
</code>
</pre>
