Working on a simple squarespace website, normally adding a background video is straight forwards however the youtube video I've been instructed to use on this website no matter what I change on the parameters for the video or using z-index on the site display the content on top of the video in IE and FireFox yet Chrome works no problem.

Help!
P.S. You will need to enter as a visitor.
Youtube videos are Flash. Flash has seniority over the Z-order so it is "always" going to overlay.
I had the same issue once and solved it by using
wmodeattribute. Try adding?wmode=opaqueto the URL or&wmode=opaqueif there already is a parameter.
