Hi Kellie,
Good first go at CSS!
The page looks fine to me in IE7. I might suggest Safari (for Mac or Windows) and Opera if you really want to get technical (but things *always* look funky in Opera it seems.)
On thing - the logo isn't showing up - just the alt tag and little X showing an image wants to be there. All in all, so far so good (but don't forget to do major
SEO on this site - it's likely a super small local niche so should be pretty easy to take the top spot for Nashville's school uniform market.)
