in the directory where you installed vanilla, navigate to themes/vanilla/styles/default/vanilla.css. back up the style first if you want to (copy the default folder, and name it something else, such as MyStyle). once the stylesheet is open, add this to it:
I did it by simply deleting ".DiscussionActive" from vanilla.css
opened vanilla.css up and did a search for ".DiscussionActive" and deleted it.
Of course I backed up my original css file.
Comments
.DiscussionActive { display:none; }
and that should do it.
