I have a layout that is working, but it has one very annoying problem.. when the content is taller than the screen, the background stops.
This is the desired layout in bad-ASCII-art format:
_____________________ _ | | long |logo| | | | content | | | | | | | | | | | | | |grad| |grad| | Viewport | | | | | | | | | | | | | | _| | | | | | | | | _____________________ |2em| <-20em->| 2em|
..or with short content..
_____________________ _ | | short |logo| | | | content | | | | | | | | | | | | | |grad| |grad| | Viewport | | | | | | | | | | | | | | | | | | | | _____________________ _|
Basically it looks like a single column, with a glow as a column either side. Over the left-glow is a logo. When the content is short, it is still the full-height.
I have tried using the CSS min-height hack, which fixes the middle column, but then the gradients only extend as far as the content (in the left column, a single , in the right column the logo)
Here is what the layout looks like:

And the problem (when the browser window is shrunk vertically):

Finally, the problem HTML/CSS, http://data.dbrweb.co.uk/tmp/fifestock_layout_problem/
Given that you have your gradients in seperate columns to the left and right, you need to implement ‘faux columns‘.
