# computer code

code: For marking up generic pieces of computer code.
pre: For retaining whitespace (generally code blocks) — if you use indentation or excess whitespace inside your text, browsers will ignore it and you will not see it on your rendered page. If you wrap the text in - tags however, your whitespace will be rendered identically to how you see it in your text editor.
var: For specifically marking up variable names.
kbd: For marking up keyboard (and other types of) input entered into the computer.
samp: For marking up the output of a computer program.

<pre><code>var para = document.querySelector('p');

para.onclick = function() {
  alert('Owww, stop poking me!');
}</code></pre>

<p>You shouldn't use presentational elements like <code>&lt;font&gt;</code> and <code>&lt;center&gt;</code>.</p>

<p>In the above JavaScript example, <var>para</var> represents a paragraph element.</p>


<p>Select all the text with <kbd>Ctrl</kbd>/<kbd>Cmd</kbd> + <kbd>A</kbd>.</p>

<p>There once was a man named O'Dell<br>
Who loved to write HTML<br>
But his structure was bad, his semantics were sad<br>
and his markup didn't read very well.</p>
