Values have the > following meaning: I'd propose one substantive change: I think that it should affect how the element is aligned in its parent, not how the children are aligned within the element. Second, I'd defer to the formal definition of computing heights and margins to define how it works -- and this definition would make this (inherited) property weaker than auto margins. Thus I'd rewrite this as: This property describes how block boxes: 1. without 'auto' side margins, and 2. smaller than the width that would fit in their containing block are aligned within their containing block when they have no 'auto' margins. This property aligns blocks by changing the margins that are used in the section on <a href="http://www.w3.org/TR/CSS21/visudet.html#Computing_widths_and_margins">computing widths and margins. > left > Aligned all element boxes to the left > > center > Center aligns all element boxes > > right > Aligns all element boxes to the right I'd say: left If neither 'margin-left' nor 'margin-right' is 'auto', 'margin-right' is treated as 'auto', aligning the block to the left. center When neither 'margin-left' nor 'margin-right' is 'auto', both are treated as 'auto', aligning the block in the center of its containing block. right If neither 'margin-left' nor 'margin-right' is 'auto', 'margin-left' is treated as 'auto', aligning the block to the right. start When 'direction' is 'ltr' ('rtl'), the same as 'left' ('right'). end When 'direction' is 'ltr' ('rtl'), the same as 'right' ('left'). -David -- L.
