Small error

[adir...@hotmail.com]

I've found a small error that happens when you have a container inside
another container. The last margin isnt removed as expected. The
solution was changing this lines:

.last {
margin-right: 0;
}

You must change his position and leave it after the span-X
declaration, including the span-x>div declaration. You also must
change a bit this line. The result would be:

.last, .last>div {
margin-right: 0;
}

Both the position and adding the ".last>div" class/element is
necessary, but i think the actual ".last" class element is not used as
the margin is asigned not to the tag that has the last class but to
his first level childs (divs).
