min-inline-size

The min-inline-size CSS property defines the horizontal or vertical minimal size of an element's block, depending on its writing mode. It corresponds to either the min-width or the min-height property, depending on the value of writing-mode.

Syntax

/* <length> values */
min-inline-size: 100px;
min-inline-size: 5em;

/* <percentage> values */
min-inline-size: 10%;

/* Keyword values */
min-inline-size: max-content;
min-inline-size: min-content;
min-inline-size: fit-content(20em);

/* Global values */
min-inline-size: inherit;
min-inline-size: initial;
min-inline-size: unset;

If the writing mode is vertically oriented, the value of min-inline-size relates to the minimum height of the element; otherwise, it relates to the minimum width of the element. A related property is min-block-size, which defines the other dimension of the element.

The min-inline-size property takes the same values as the min-width and min-height properties.
