Drawing a template using div and css or Just Table Code

SPAM I want to开发者_高级运维 design a web site interface as it is shown int this example web site which has a centred image.

I think I should use margin to put the body in the web page. the header and the footer div will be above and under the box.

the last thing is the web page is considered to be resized according to the browsers behaviour. For instance the bigger window the bigger page the slow window the small page. You may check it by resizing the windows size of SPAM how can I do it?

Probably a lot of related questions on stack overflow, but i happen to have a link on hand.
