How to use CSS (Extension) to add background color

[#1]

Hi

I have an extension where I'd like to add a special background color, or image, BUT only to a specific sheet, let's say SH01. The other sheets should have other background images.

Does anyone know how I can do this in CSS??

I have this codeline that colors the tab only, but i cannot transform it to work on the sheet itsself:

li[rel="DocumentSH01"]  a {background-color:white !important;}

Kind regards

Espen
