-	For the purpose of calculating an intrinsic size of the element

-	this value causes the element's width/height to become indefinite
-	(even if e.g. its 'width' property specifies a <a>definite</a> size).
-	Note this means that percentages calculated against this size
-	will be treated as ''height/auto''.
-	Otherwise, although this may require an additional layout pass to re-resolve percentages in some cases,
-	this value
-	(like the ''min-content'', ''max-content'', and ''width/fit-content'' values defined in [[CSS3-SIZING]])
-	does not prevent the resolution of percentage sizes within the item.
