Frustrating CSS Issues with IE7

A recent client has come back to me as some of his customers cannot view his site properly when using IE7.

Basically, there are some div elements within the header which are fine in all modern browsers, but IE7 hides some of them.

In order to attempt a quick fix, I thought the best thing to do was position the elements absolutely.
This at least makes the elements visible, but when they are viewed in IE7 their position is different than FF/Chrome etc.

Debugging is a pain as I need to use a virtual PC to see the results.

Grateful for any tips/advice

screenshot attached, with section of css below...

#intl-flags {
	width: 400px;
	z-index: 2000;
	margin: 0 0 0 300px;
	position:absolute;
}
#search {
	height: 50px;
	width: 300px;
	z-index: 2000;
	margin: 40px  0 0 300px;
	position:absolute;
	
}
#viewcart {
	height: 50px;
	width: 225px;
	z-index: 2000;
	margin: 40px  0 0 500px;
	position:absolute;
}

Craig,
Have you tried creating a less than equal to IE7 conditional style sheet to target IE6 and IE7 and positioning the absolute positioned elements using left: and top: attributes as opposed to margins? For instance:

#intl-flags {
width: 400px;
z-index: 2000;
margin: 0;
position:absolute;
top: 0;
left: 300px;
}
#search {
height: 50px;
width: 300px;
z-index: 2000;
position:absolute;
top: 40px;
left: 300px;
}
#viewcart {
height: 50px;
width: 225px;
z-index: 2000;
position:absolute;
top: 40;
left: 500px;
}

Also, is your containing element (assuming the header is a div) set to position: relative;?

Thanks for the reply Mikey.

Once I decided to make the divs absolute, I think I should have moved them outside of the header div, (but still within the outerwrapper div).

Having done so, although there are some minor spacing issues, I think it is behaving a lot better.

Give me php/mysql any day !

No problem, Craig. You can leave them inside the header, but just make sure the header div has a position: relative; attribute set on it. It will be the parent element and all containing elements will have a positioning reference starting at the top, left corner of that parent element.

I was also wondering if it was the large left side positioning/margin that was kicking them over so far to the right. But without seeing where the header's left boundary is, it's hard to gain a point of reference.

At any rate, glad its working for you.
