CSS Guru needed, clearing a DIV?

[bigred]

Hey,

I'm currently transferring everything over to Wordpress for use as a CMS for my college at uni, however the default browser on all of the uni computers is Mozilla 1.7.8 and the website doesn't display correctly. The white should continue down to the footer, leaving the grey bars on the side. See the screenshot here, http://www.dur.ac.uk/alexander.marshall/theme/1.PNG

I think its something to do with the CSS .clear DIV not working in Mozilla, so I need to find a solution. CSS really isn't my thing, so any help would be much, much, much appreciated!

Thanks,
Alex

Hey,

Thanks for your help. I stumbled across a solution just after posting, how typical

The bottom of the sidebar was originally <div class="clear"></div>
however changing that to <div class="clear">&nbsp</div> makes Mozilla render it correctly. This old version of Mozilla must ignore empty DIV's, or something, anyway I'm glad it works now
