I found the reason of this wrong behavior. The elements having class "row" inherit the width from "container", as you know, but they have a negative margin-left (-20px). The negative margin-left is balanced out with the margin-left of the elements having class "span*" (20px)
In our case we had: <span12> margin-left = 20px <row> margin-left = -20px <span9> margin-left = 20px obtaining a margin-left total of 20px Removing ".span12", things are balanced out again. Therefore, as Annet noted, we have to strictly follow bootstrap layout: "span*" elements wrapped in a "row" element. Latter statement is clearly showed in "Nesting columns" paragraph at http://twitter.github.com/bootstrap/scaffolding.html#layouts Last trunk of web2py has layout.html corrected.
