I’m not certain how amenable header tags are for styling in custom.css. Certain tweaks seem to fail, even with the !important flag.
For example, I’m able to change “text-decoration”, but not “font-weight”, so far as I can tell.
Is full CSS supposed to be supported? If there are limitations, are those documented somewhere? What might I be doing wrong? Are there custom.css swipefiles online, that we can use instead of downloading whole themes?
I’m not skilled enough to write an actual theme, so I’m left doing very rudimentary things in CSS, but I do understand that basic CSS pretty well.
