Here is a tip to center your whole design on your page.
Code:
<html>
<body>
<table cellpadding=0 cellspacing=0 width=”100%” height=”100%” valign=middle align=center><tr><td align=center>Put all your content here.</td></tr></table>
</body>
</html>
Change the width and height to your preferences.
Add your content and you are good to go.
