Hello guys! I'm making a site and I want to add a mouserover effect on the social-network icons, exactly like what WinRumors (http://www.winrumors.com/) have on their social icons. To understand what I mean (and what I want), open the WinRumors site and place your cursor on top of any of the social icons (twitter, facebook...).
I've tried searching an how-to over the web, but haven't found anything like that. I don't know how to do it by myself, so I'm asking people that know much more here.
Can someone help me? Thanks in advance!
