<p>Maybe use a slightly more practical example.</p>
</comment>
<p>An example of a custom CSS:</p>
<code><![CDATA[
body{
/*Make everything upside-down*/
-webkit-transform: rotate(180deg);
}
]]></code>
<p>Your custom CSS will override the style sheet on pages which you visit
after you enable it.</p>
</page>
