wrap it in <center> tags?
Sadly, the <center> tag is considered obsolete :(
To center a control now you'll have to place it in a <div> or Panel (which renders as a <div>) and set it's style to be style="margin-left:auto; margin-right:auto; width=50%" (note that you have to set the width).
This will center it horizontally but not vertically.
You'll have to use JavaScript to center it vertically.
You can center Text though by setting the line-height style for the <div> to be the same as the height of the <div>. One warning: if you have multiple lines of text this will not work.
I'm very disappointed that the <center> tag has become obsolete and am eagerly waiting for the day when CSS can achieve what the <center> tag used to.
