First , put together your basic HTML Code. Nothing complicated , but it should probably look like this;
CODE
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta content="text/html; charset=ISO-8859-1"
http-equiv="content-type" />
<title>Your Site Name</title>
</head>
<body>
<div id="layout">
All but All content should be here
</div>
</body>
</html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta content="text/html; charset=ISO-8859-1"
http-equiv="content-type" />
<title>Your Site Name</title>
</head>
<body>
<div id="layout">
All but All content should be here
</div>
</body>
</html>
The ID is important. It doesn't matter what you ID/Class it as , as long as it has a value/Id
. The entire tutorial is useless otherwiseOpen a new CSS file , or make a new one in notepad
CODE
body {
text-align: center;
}
#container {
margin: 0 auto;
width: abcpx;
text-align: left;
}
Body defines the entire document. The Body text align; center is used for the general code.The container tag defines the container ID we declared earlier
.The Textalign left means all text within the container will be aligned left 
. The Margin tag defines no Margins on top or bottom but auto margins on the left. So replace Abc with whatever width you care to add , and the layout will be centred according to that width.That's essentially it. There are several other tweaks , but aren't really neccesary. Hoping I helped in some way , Encryptedwrath
NOTES:
1) The text align is compulsary for IE users. Other browsers display the code fine without it
