CSS, centering links inside div

Wrap the links in another <div style="width: 300px; margin: 0 auto;"> to group them together.

If you need shrinkwrapped centering, apply inline-block on the things you want centered. Then text-align:center; on the parent.

You'll need to probably have a workaround for IE, but as you haven't posted code I won't go into that.
