Thank you waybackmachine! Fixed link

An excellent and very elegant hack that allows you to use the :focus pseudo-element in CSS2 for any selector, in MSIE. Right now IE only supports :focus on anchors. The article shows some good examples for styling focused form fields. Also included in the hack is the whatever:hover behaviour since IE has a similar deficiency with this pseudo-element.

Someday I need to use some of these cool techniques on my site.
