I'm not sure what happened to my layout. In IE the categories and text in some of the posts is huge. It's fine in Firefox. http://obsessionfitness.com I can't figure this out and would really appreciate any help. Thanks.
You need to specify a text-size in the css when using header tags. IE has a different idea of what size each header tag should be to FF.
Turns out it was within the Wordpress Admin, not CSS. Adding an H2 header to the <!--more--> tag caused the problem. Thanks.
