I have been running into some issues with ul and other content. The content is spanning beyond the confines of the wrapping divs, resulting in overlapping.
I have had this issue many times before outside WordPress, and simply fixed it with either a clearing div (at the end of the content or with :after pseudo) or in some cases overflow: auto. However, in this case, none of those methods seem to be working.
The site can be found here: http://insideart.net.au/
You can see the sidebar (float: right;) hangs well below the wrapping div and the same applies when lists, etc. are displayed in the posts (float:left;) with jQuery Masonry.
Any help in solving this matter would be greatly appreciated.
