and 'left' is set to static position and 'width' and 'right' are 'auto', then the used value of 'width' is given by 'shrink-to-fit' width calculation. If 'width' of an floating, non-replaced element in normal flow computes to 'auto', then the used value of 'width' is also given by 'shrink-to-fit' width calculation. If 'width' of a floating, non-replaced element in normal flow is given by 'shrink-to-fit' width calculation, then such calculated width can be furthermore constrained, reduced by a max-width decl
