I added a YouTube video in an IFRAME to the top of this page
. Seems to work fine, but dropdown items from the navbar below the header go behind the IFRAME and are not visible. (This occurs in IE and Chrome. In Firefox, the nav items appear on top of the video.)
I've tried experimenting with the z-index of the iframe, but I haven't hit on anything that makes any difference on IE or Chrome.
Any ideas? Thanks.
