Webpage sizes!

When making webpgs in PS wats the correct size ?? i dont want my website in top left like this, http://i.1asphost.com/mtgleague/test/index.html

i want it in the middle !! but i cant seem to get it, by the way ii have Dreamweaver if that would help.

Just stay under 800 px in width and you should do just fine.
To center the layout just but a < center > after the < body > tag.
Never used dreamweaver, but you can type in < center > there too..
Without the spaces offcourse...

Actually the correct way to do it would be to use < div align="center">< /div> (without the spaces after the first brackets). < center> isn't a valid HTML tag anymore, plus you have to have a closing tag.

Or you can do it with CSS, which is by far the best way.

#container {
margin: 0 auto;
width: 780px;
}

Then in your HTML you'd have

< body>
< div id="container">
Your site here
< /div>
< /body>

Emm lol its not working!!!!!! i copyed at pasted wat iit said there , so a litlle more in depth would be good
