CSS Tutorial for Compliance

Does anyone know of a good CSS tutorial for compliance? I've made some
of the suggested fixes, but I still am throwing some errors.

On another site I have validated, the CSS is perfect. But when using
IE7 I continue to get browser errors (locks up) if I click on too many
links. Maybe the problem is isolated to this PC, or worse yet a buggy
IE7. Any suggestions or is IE7 just a lost cause? :)

Thanks for your help.
