If you have a left-floated navigation bar, and a main content column, you may notice that when "clear: both;" any content within the main content column, it will drop it below the navigation bar.
There are two solutions:
- Float your main content div as well. This may require other CSS changes.
- Add "overflow: hidden;" to your content div. See below:
#column-left { float: left; width: 185px; }
#content { margin-left: 200px; overflow: hidden; }
