The featured projects on the right is slightly out of line - the images over hang the coloured block below. It looks fine in the other major browsers and fine in IE7 surprisingly.
I have attached the CSS (.txt file) - apologies for the messy code.
The site’s built on Joomla and the Featured articles are created using the ‘Mini Front Page’ extension. The extension uses tables unfortunately. I was tempted to hack about with it a little and use divs instead of tables but my PHP skills are next to none so I was afraid of damaging the templates.
