it is possible: .page-Fandom_Open_Source_Library { color: lime; } actual implemetation can be different. since op still gave not any info, it is hard to say how exactly this styling must be implemented.

i personally believe op already has all tools to achieve his goals. he just can't implement it right. that's why i asked op about links, examples and actual puproses. there may be many ways to do... but we just do not know what, cuz op gave us nothing but ".mainpage" he want to stick for no visible reasons.

and, yes, by currently provided info it is seems like impossible with just css. i don't say it impossible at all, i say it impossible because of lack of info provided by op.
