minmax()

{{CSSRef}}

The minmax() CSS function defines a size range greater than or equal to min and less than or equal to max. It is used with CSS grids.

{{InteractiveExample("CSS Demo: minmax()")}}

grid-template-columns: minmax(20px, auto) 1fr 1fr;

grid-template-columns: minmax(0, 1fr) minmax(0, 1fr) minmax(0, 1fr);

grid-template-columns: minmax(2ch, 10ch) 1fr 1fr;

<section class="default-example" id="default-example">
  <div class="example-container">
    <div class="transition-all" id="example-element">
      <div>One. This column has more text in it.</div>
      <div>Two</div>
      <div>Three</div>
      <div>Four</div>
      <div>Five</div>
    </div>
  </div>
</section>

#example-element {
  border: 1px solid #c5c5c5;
  display: grid;
  grid-gap: 10px;
  width: 250px;
}

#example-element > div {
  background-color: rgba(0, 0, 255, 0.2);
  border: 3px solid blue;
  text-align: left;
}

minmax(max-content, 200px)
minmax(auto, 300px)

A function taking two parameters, min and max.

Each parameter can be a <length>, a <percentage>, a <flex> value, or one of the keyword values max-content, min-content, or auto.

If max < min, then max is ignored and minmax(min,max) is treated as min. As a maximum, a {{cssxref("flex_value","<flex>")}} value sets the flex factor of a grid track; it is invalid as a minimum.

Values

{{cssxref("<length>")}}
- : A non-negative length.
{{cssxref("<percentage>")}}
- : A non-negative percentage relative to the inline size of the grid container in column grid tracks, and the block size of the grid container in row grid tracks. If the size of the grid container depends on the size of its tracks, then the <percentage> must be treated as auto. The {{glossary("user agent")}} may adjust the intrinsic size contributions of the track to the size of the grid container and increase the final size of the track by the minimum amount that would result in honoring the percentage.
{{cssxref("<flex>")}}
- : A non-negative dimension with the unit fr specifying the track’s flex factor. Each <flex>-sized track takes a share of the remaining space in proportion to its flex factor.
max-content
- : Represents the largest max-content contribution of the grid items occupying the grid track.
min-content
- : Represents the largest min-content contribution of the grid items occupying the grid track.
auto
- : As min, it represents the largest minimum size (as specified by {{cssxref("min-width")}} /{{cssxref("min-height")}} ) of the grid items occupying the grid track. As max, it is identical to max-content. However, unlike max-content, it allows expansion of the track by the {{cssxref("align-content")}} and {{cssxref("justify-content")}} property values like normal and stretch.
