Problems with CSS on Firefox

[Subfusion]

Right, I'm having some small problems with CSS. Basically, IE displays the design just the way I want it to look like whereas, Firefox doesn't.

I need help is sorting this out, I have attached an archive with the html and css file in it.

This is how the website should look correctly, it's a screenshot using IE:

This is where my problem arouses, when using Firefox:

Removing this line :

background: #666;

from your Body tag solved the problem for me here in firefox

The thing is, I want the background to be that grey color, and the header white.

Ok. Forget my first post, and add this line to your wrap tag :

height:80px;

You might want to fix that ;).

I had this problem many times when I was trying to do CSS ages ago. The problem is, if the only content in a div is another div, then for some reason Firefox does not count the second div as being in the first div. I can't remember whether I found a solution to this or not.

To see what's happening clearer, add a 1px border to each div, you will notice that the two at the top are just 2px thick lines because they have nothing in them. This is one thing that made me really confused with CSS.

Try adding widths and heights. If you are using floats, make sure to clear them either with css or just breaks with clears on them.

add this line to your #wrap tag :

height:80px;

IT works

The height tag is going to change, because in #container (Which is in #wrap) will have different heights, as my posts are going right below #heading and #nav.

Edt: I should have said this before, by anyways. If you take a look at http://mattbrett.com/ that's what I'm trying to do, the header and the main post has a white background and the bottom grey part will have links to my del.icio.us account and other stuff.
