When using the
banner-position: top-fixed (setup.yml) a video that is included through the youtube-player.html widget will scroll in front of the banner/menu content.
Include the video directly in markdown using iframe’s.
The drawback is that the video will not auto-resize with the width of the column, and likely you will need to specify a height/width for the video in the iframe specification.
_data\setup.yml was updated to include a recommendation not to use the youtube widget for top-fixed.
