max-inline-size

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The max-inline-size CSS property defines the horizontal or vertical maximum size of an element's block depending on its writing mode. It corresponds to the max-width or the max-height property depending on the value defined for writing-mode. If the writing mode is vertically oriented, the value of max-inline-size relates to the maximal height of the element, otherwise it relates to the maximal width of the element. It relates to max-block-size, which defines the other dimension of the element.
