Website layout

Hi, I'm trying to do a site, and I'm wondering how could I do a basic layout with the background image covering all the screen and a little menu of "height 30px" at the bottom, I want to do it in all the screen but i would like to adapt to all resolutions without scroll bars, I don't know how to do it, and I want to minimize and have a good structure without the scrolls bars or the layout becoming tiny and plenty of white space... I don't know how to explain... "Basically I want to do that... http://ancoreventos.com/#!/contactos/ A panel in the center, a menu in the bottom, the background covering all the screen and minimize with no appareance problems Thank you...
