Hi, I want to implement a link to switch on and off an image placed on top of the site so you can see the relation of the design to the grid, Kinda like what the grid system has on their home page, they switch the background-image on the body, since their site is white it works toggling the image as background but in my site part of the grid would be hidden by some dark divs, so I think a solution could be to place it on top of everything, I could use jquery I guess, I have been trying to find a tutorial online with no luck, anyhelp would be appreciated, thanks.
