Looks fine from what I can see, a few things you might want to fix...
Code:
<LINK href="css/grids.css" rel="stylesheet" type="text/css">
Lowercase link not U/C
Code:
A:link {text-decoration: none; color: #0099FFl; }
Make your A: lowercase and 0099FFl isn't a colour
(Welcome aboard and best of luck)
