Hi all,

I'm developping a page with a lot of graphic elements, grouped in two colums.
The page got a fixed header, that gets loaded last, so all other elements disappear under it while scrolling.

In the left column I call Youtube videos with Javascript. I shows fine, unless that in IE - but not in FF or GChrome - the images that are supposed to disappear under the title go over it.

This the page address: http://www.clermont-herault-concerts...them_media.asp

Any idea how to avoid it?
PS: I know there is another problem with that page: the mp3's in the right column aren't found by IE - but FF and GC finds them! - but I think this had another cause.
Hereunder a few elements of the html and CSS codes:
