Small bit of CSS help please

[HappyFace19]

Hello, could somebody have a quick look at my css code for me please, and help me with this problem. What i am trying to do, is have my content box (content area) the same height as my menu. At the moment the content area expands when you put text or data in, I would like it to be a set size, matching up with the bottom of my menu.

The header and the contentarea boxes also stretch and shrink to fit the page, depeding on the screen size. That is fine, but i would like it to be a set size for height.

Hope i am explaining this correctly. Here is a screen shot of my page, note the small contentarea box, as it has no data in..... need it to match up with my menu. CSS attached also. Thanks

Why don't you just set a height for div#contentarea?

[HappyFace19]

Yep, got it ... I set the height in div.content.

Thanks
