how to fix site for IE7

I am having tough time finding out what CSS property to change to get my page working in IE7.

Page is here

It works fine in Firefox, Chrome, IE8 but not in IE7 (maybe IE6) as well.

Notice that navigation menu goes up and #header that conta开发者_如何学Cins logo shrinks to a small size...

Your .content has a height of 4.2 pixels. Try using a border-top:4px solid #whateverhex instead of using a 41px high repeating gif.

Then remove height:4.2px.

Alternative would be #nav { clear:both; }

my guess is that IE isnt using the Psuedo after class, which is where you clear your float. you can just add a height to the #header, or clear your float in a line break tag after the content.
