Center entire page in browser

[passingthrough]

How can I center a fixed width page in the browser window without tables?

I've tried the fixes in existing posts, but they don't seem to do it here.

Thanks

Hello passingthrough,
Your on the right track by using margin left/right auto and using a doctype... it's trying to center your #content but the 1800px width is just too wide.
Narrow that down to 900px or so and see -

div#container
{
   width: 900px;
   position: relative;
margin: 0 auto;
background: #000;
height: 3000px;
   text-align: left;
}

There is still plenty of other problems though. All the absolute positioning is really messing things up. Try removing the height:3000px; and you'll see the black background disapear.

Run your code through the validator and see if fixing as many errors as you can doesn't improve things - see my suggestion and links about validating in my sig below.
