Using a browser inspection tool is the only way you are going to find out the classes without searching through the templates in the ACP.
Chrome has one built in.
Okay so, I have another problem.
I've tried to edit the color of the link in messages when you hover over them, But whatever I do, I cannot remove the annoying box shadow.
Here's a screenshot.
Additionally, I'm struggling to change the link colors in some css, As it seems it's prioritizing the base link CSS code.
Oh my god. It worked. Thank you so much!
I want to change the text colour of the titles of the read threads. I've tried using the !important code in discussion_list.css but to no avail.
EDIT: Also, I just added that code, And that changes the colour to the subforums. I want to change the colours of the actual threads when they are read.
