css single-line layout with flexible width (tricky)
i'd like to make a single-line css layout which flows to the right indefinitely. 
each box would have a certain percentage (e.g. 20%) of the viewport width. 

this is much easier to explain with a picture: 

    +-----------------------------+
    |VIEWPORT                     |
    |                             |
    +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ 
    |BOX| |BOX| |...| |   | |   | |   | |   | |   | |   | |   | 
    +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ 
    |           |<--->|           |          
    |   20% of the viewport width |
    |                             |
    +-----------------------------+



*why would i want to do this?* 
i have a site which displays a calendar (as a grid, http://bit.ly/xnOSMN) and i'd like to offer an alternate view. 
there would be seven boxes visible (the current day being in the middle). 
i'd use javascript to offer left/right buttons that scroll exactly one box to the left/right . of course i could do the box sizing with javascript too, but i'd very much prefer a css solution.
