I am currently working on a site and when you roll your mouse over the right hand part of the screen the whole site shifts to the left. I have no idea why it's doing this...
If anyone could help that would be awesome. I also have noticed Firefox isn't displaying a lot of things correctly...so help of some sort would be great!
Well, the first thing I’d do is fixing possible HTML errors the validator comes up with. Valid code is a good first step to a functional site. Maybe this will fix the issue(s) already and if not, at least you can say it’s not wrongly nested tags that cause the issue.
