damn floats...

Can somebody help me please?

I'm working on a new website and I've decided I'm going to do everything I can to ensure that it's standards compliant, accessible and quick loading.

So, I'm using a CSS based design, however I have a problem.

The layout is in a blog format, only each entry has an image aligned to the right of the paragraph showing an icon for the category. The problem is, is that if the entry is pretty short or the user has a wide screen the image pushes past the bottom of the entry and forces the image on that entry over to the left.

You can see what happens at http://www.na5ty.com/index.php

I must warn you though, this site does contain some foul language and links to sites that not everyone may agree with.

Does anyone know of any CSS stuff that I can use to combat the problem? In days of old I would have just stuck each entry in its own table row, but I can't really do that with this method of design.

Thanks for any help you can offer.
