Placing your Snippet on a Wix site
So we can't, obviously, create a bar that spans the page as everything is restricted to a Wix frame - It is done on purpose by Wix.

You CAN place our bars on your Wix pages using using the 3rd Party Overlay - now called S.M O T. - and overlaying your own pages with the bar
