Admin Forum:CSS/JS span tag

Hi everyone! I'm here to ask if one can make (or similar) tag in CSS/JS? I want to add a highlight system to Locomotive Wiki I'm an admin on, and I'm fine with the syntax for setting up the highlight, but I'm interested to know if there is a way I can get a mouse-over the userpage links to say "This user is the Founder" or "This user is an Administrator" etc. Is there a way to get the a:hover (CSS) or onmouseover (JavaScript) to display such a title? :)

PS I don't know anything about JS yet, but I'm begining to pick up CSS!
