`min-inline-size` CSS property

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.

min-inline-size: 200px;
writing-mode: horizontal-tb;

min-inline-size: 200px;
writing-mode: vertical-rl;

min-inline-size: 20px;
writing-mode: horizontal-tb;

min-inline-size: 75%;
writing-mode: vertical-lr;

<section class="default-example" id="default-example">
  <div class="transition-all" id="example-element">Change min-inline-size</div>
</section>

#example-element {
  display: flex;
  flex-direction: column;
  background-color: #5b6dcd;
  height: 80%;
  justify-content: center;
  color: white;
}

Syntax

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

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

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

/* Global values */
min-inline-size: inherit;
min-inline-size: initial;
min-inline-size: revert;
min-inline-size: revert-layer;
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.

Values

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