Hi David Whritenour, I've made some tests on .sf_cols and there was absolutely identical behavior on IE8, Chrome 9, Opera 11, Safari 5.0.3 and Firefox 3.X - no extra padding added below or above.
You can provide us your CSS file or a link to your live project to check where is the problem. Best wishes, Jordan the Telerik team
.sf_cols:after content: none!important
I did not not know we could override the builtin classes like this.
Anyways, this seems to have done the trick. Thanks for the help!
