width: 100% X max-width: 100%

Why not to use just width: 100% instead of max-width: 100%?

Those mean different things. A "width: 100%" setting would require the element to span the entire window and force it to expand to fill (or shrink to fit) the space.

But "max-width: 100%" would still shrink the element to fit if it was too large, but it would not cause the element to expand if it was smaller than the full size.
