Customizing the Autoscrolling Icon
Tom was playing around with FireFox yesterday and came to the realization that the auto-scroll icon is actually inserted dynamically into the document’s HTML, but outside the HEAD and BODY — meaning it’s still within the clutches of our evil CSS.
Mwha Ha Ha HA!!
Try clicking your middle mouse button anywhere onscreen in FireFox 1+ to see the results.
Here’s the CSS:
html>img
{
width: 0!important;
height: 28px!important;
padding-left: 28px!important;
background: url(/images/icons/autoscroll2.png);
}
In reality this is a known bug, so can’t really be relied on into the future (though it’s been around for a long time), but if your client is looking for that little bit of extra branding…
