Question

Is there an easy way to have a “glass pane” all over the HTML page, regardless of zoom/slide events/platform/browser{mobile/desktop}?

By “easy” I mean something like pure CSS support, not a plug-in.

Fallback: plug-in advice might be useful as well.

Thanks

If you just mean a layer on top of everything, try this:

#top-layer {
    position: fixed;
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
    top: 0;
    left: 0;
}

You can set opacity: 0.5; if you want it semi-transparent.
