Fill remaining space with left div

[Tatasoido]

Can anyone tell me how to make a left div fill the remaining space, without fixing the right div size.I want the exact opposite of the following example:\[code\].left {float: left; border: 1px solid blue;}.right {overflow: hidden; border: 1px solid blue;}\[/code\]The right div should take only the size it needs, the left div should take all the remaining space.
