Use site style sheet to ONLY influence journal overview site

Hi all,

I was wondering if there was any way to use the site style sheet (the one found under Administration > Site Settings) to do some CSS design work for the overview page listing all your journals (specifically I want to adjust the footer background colour on just that page) without it influencing the styles of all journals.

I know I can override site wide CSS with !important, but it’s a bit of a hassle to add a style sheet to every single journal that doesn’t use the same footer colour.

I’d appreciate any and all tips you can give me! (Note that I don’t want to fudge around in the theme or source code, just the style sheet CSS or normal backend settings if possible)
