1. margin:auto horizontal centering is not supported in IE6. Instead you can either use absolute positioning to center or you can do

   body{ text-align:center; }

2. For IE min-height you need to add the hacked property _height: 300px in addition to min-height: 300px; All browsers but IE will ignore the hacked property, and since IE effectively treats height as min-height, you’ll get the effect that you want in all browsers.

3. background-color works in IE without any problems.
