center text in div

Answer 1

Do you mean vertical centering, horizontal centering or both?

Horizontal centering of inline content is easy. Just apply text-align: center to the containing block. Centering horizontally a block within another block with CSS is typically done with:

#centerMe { margin: 0 auto; }

Note: on IE6 this requires that IE be in "standards compliant" rather than "quirks" mode. To force this always put a DOCTYPE on your HTML document. For example:

Vertical centering is much worse.

You may want to look at Vertical Centering in CSS. This is actually a non-trivial problem. The vertical-align style property you're using only applies to table cells (in a cross-browser backwards compatible way). This would be trivial to do with a table for what it's worth.
