Can you be more specific about what aspect of this isn’t working for you?
I’ll take a guess that your problem is getting the video to extend up to the top of the page. If that’s the case, here’s a solution.
Place the video player in the section immediately below the header, docked to the top of that section. Then give it a negative top margin equal to the height of the header.
Here’s an example, where the header is 60 pixels tall. Notice the docking line (top circle) which shows that the video player is docked to the top of the section below the header, but extends above that section and behind the header. And note in the sidebar, I’ve set the top margin to negative 60 (-60), which is the height of the header.
Negative docking margins can be very useful, extending objects outside containers, sections, or gridlines.
Is this the problem you are having, or is it something else?
