Hi Robin,
I could do a child theme and CSS if that’s necessary but I am trying to figure out whether it is actually necessary.
If you look at the page I’ve linked to – the topics index for the single forum on my website I believe – then I assume you’ll see the same as me, which is that there is the massive page title, which is default Twenty Twenty theme like the rest of the website, and there is the tiny bbPress text, inc. forum information, pagination text, topic title etc.
I tried changing the forum information font size in the Topics Index Styling tab but it had no effect. Am I using the wrong bbPress Style Pack tab?
