On my site there is a static div which functions as a header. Where there is a youtube video also on the page and the user scrolls down, the youtube video covers the header, even though it has a much lower z-index value.
How can this be rectified so that the embedded video appears below the header at all times?
Thank you
Had this problem myself a while back.
You need to add a wmode parameter with the value of opaque, ie
wmode="opaque"
