html - z-index and iFrames!

Question

I'm using the FancyBox plugin for some of my site's images. On one of my pages, I also have the embedded iFrame code from YouTube to place a video on the page.

On this same page is a thumbnail that, when clicked, FancyBoxes the image. However, the embedded YouTube video still lays over the FancyBox image. I did a bit of z-index experimenting and still no luck.

Does an iFrame have seniority over all elements in a page even with z-index set, etc.?

Answer 1

Add wmode=transparent as param.

Html solution

<iframe title="YouTube video player" 
width="480" height="390" 
src="http://www.youtube.com/embed/lzQgAR_J1PI?wmode=transparent" 
frameborder="0"
>

jQuery solution:

$(document).ready(function () {
    $('iframe').each(function(){
        var url = $(this).attr("src");
        $(this).attr("src",url+"?wmode=transparent");
    });
});
