add logo 'on top of menu/header image

Hello, I would like to put a logo image on top of the header image and menu, like explained here: http://amethystwebsitedesign.com/add-logo-on-top-of-navigation-menu-in-a-genesis-child-theme/ (found that link here: http://cobaltapps.com/forum/forum/main-category/web-design-talk/15497-how-can-i-float-my-header-image-over-top-of-my-menu-bar ) would that be possible with catch evolution? Thanks Pieter
