As with the HTML, I have created a CSS template which may be of use. The idea is to clear everything back to default across all browsers by removing padding, margins and setting the fonts up properly.

* { margin:0; padding:0; }
body { font-family: "Trebuchet MS", Verdana, Helvetica, sans-serif; font-size: 100%; }
.access { display: none; }
.clear { clear: both; }
a { color: #000; }

/** Structure **/
#container { width: 790px; margin: 0 auto; }
