I'm a noob when it comes to coding; I just wanted to know if/how I can attatch a behavior (i.e. appear/fade) to CSS? I want to apply the same effect to multiple tags (i.e. for when each image has the Mouse Over). I'd appreciate the help!
Transitions can be achieved with CSS3, but browser support is still spotty (http://www.w3schools.com/css3/css3_transitions.asp for more info/examples). My impression is that, at this point in time, anyway, it's still a better idea to use javascript for these behaviors.
Use the search function to look up "psuedo elements" for pure CSS only animation
