Center Divs In a Div

[LikeStuff]

I have 3 divs in Div2 and I'm trying to get them to center but it doesn't seem to be working for me. Can someone tell me what I may be missing. So Div1 is the main div, Div2 is in Div1 and the 3 divs are in Div2. This is my CSS.

#Div1{
width: 960px; margin: 0 auto 0 auto; text-align: center; overflow:hidden; clear:both;}
#Div2{
width:100%; margin: 0 auto 0 auto; text-align: left;}

Thanks!

What I've done in some instances is put a <center> tag in the index file.

<center>
divs
divs
divs
</center>
