Hide or change color of Resume screen.

Hi,

i hide the player buttons to made the interface by myself in some EAD resources. I will use a lot of the resources on Rise 360 course. But the resume screen on it, made my Rise pages look very strange with a lot of  "black squares".

I can put a background image and change color of the resume button using CSS of a HTML publish. But on Rise 360 i cant use it.

How can i hide this resume/restart screen or put some background on it?
