How do I make a table that spans across, so that I can put a nav. bar in it... like here:Clickie (http://www.sitepros.net/kenshin/)

Also, how do I change the colors like so?

Clickie (http://www.sitepros.net/kenshin/)

if you want it to span completely accross no matter what the clients resolution then use

<table width="100%">

to change colours... can be done like

<td bgcolor="#hexcode">
and you can change borders..

For your first question, add this to your starting BODY tag...

topmargin="0" leftmargin="0" marginheight="0" marginwidth="0"

Then go with the previous post by klidifia.
