Viewer overlays archive list

So I noticed from a previous post that you can change the CSS so that it will not be displayed over the archive list.

.fluid-width-video-wrapper object {
position: relative;
}

However, now that it is relative, the viewer doesn’t show up at all in Internet Explorer or Mozilla Firefox. Can the author help me out with this? I like the format, but it’s not that useful if it is not compatible with multiple browsers.

Okay I fixed it. This works better:

.fluid-width-video-wrapper iframe, .fluid-width-video-wrapper object, .fluid-width-video-wrapper embed{
position: relative;
}

That is compatible with both Mozilla and Internet Explorer.
