Shadow behind the navigation bar code?

Hi, I was wondering if there's a code I can use to get a shadow behind the images of my navigation bar. I made it myself, and I really don't want to redo every button by putting a shadow behind it, so if there was a code for it, that would help.
If there is a code, can someone post it? My forum type is phpBB2.

this is the css for shadow

Code:


moz-box-shadow: 0px 0px 12px #666666;
  -webkit-box-shadow: 0px 0px 12px #666666;
  box-shadow: 0px 0px 12px #666666;



Thanks, what do I put in there to get it behind the navigation bar?
(I'm pretty much clueless at CSS)

You should have in CSS something like navlinks or someting

well this is a guess tbh i not look at phpbb2 forums for some time

Code:


.mainmenu img{
moz-box-shadow: 0px 0px 12px #666666;
  -webkit-box-shadow: 0px 0px 12px #666666;
  box-shadow: 0px 0px 12px #666666;
{


but to find out elements class or id names (chrome) you simple right click on your mouse and click inspect elements
