HTML & CSS
I know how to make rounded corners using css for a liquid box that extends as the browser extends. (sliding door approach)
But would people suggest this is the best method for the overall wrapper as it is so big?
It is certainly feasible. You might like to have a look at a recent demo page by Eric Watson. It could easily be adapted to your purpose.
Of course, you could use CSS3 rounded corners... as long as you are willing to sacrifice IE users. (Yhat's what I tend to do, but you may not be allowed to. )
EDIT: actually, on second thought, if I had to use images, I would probably have a separate strip at the top and bottom of the site and perhaps use the doors as you suggest.
Hi, until multiple imges are supported you wil be required to have many elemenst to hold all the images
Ralph can give you CSS3, however all of IE will be outa the loop, as well as Opera
