CSS for Page References only if they are Highlighted

Hi, I’m new to logseq and I’m trying to customize my CSS for the first time.
I think this question might be simple, but I’m not getting there :smile:

Is it possible to bold my Page References only if they are Highlighted?

I’m trying to use the code:

mark {
font-weight: bold;

and the a.page-ref but I can’t seem able to get them to work together.

Can anyone give me a tip?


Just in case…

Thanks @Didac, that’s nice to know.
But I still wasn’t able to get it to work because my CSS knowledge is very low.
