This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The minmax
()
CSS function defines a size range greater than or equal to min and less than or equal to max. If max < min, then max is ignored and minmax(min,max)
is treated as min. As a maximum, a <flex>
value sets the flex factor of a grid track; it is invalid as a minimum.
Syntax
/* <inflexible-breadth>, <track-breadth> values */ minmax(200px, 1fr) minmax(400px, 50%) minmax(30%, 300px) minmax(100px, max-content) minmax(min-content, 400px) minmax(max-content, auto) minmax(auto, 300px) minmax(min-content, auto) /* <fixed-breadth>, <track-breadth> values */ minmax(200px, 1fr) minmax(30%, 300px) minmax(400px, 50%) minmax(50%, min-content) minmax(300px, max-content) minmax(200px, auto) /* <inflexible-breadth>, <fixed-breadth> values */ minmax(400px, 50%) minmax(30%, 300px) minmax(min-content, 200px) minmax(max-content, 200px) minmax(auto, 300px)
Values
- <length>
- A non-negative length.
- <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 asauto
. The UA 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. - <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 a maximum, identical to
max-content
. As a minimum it represents the largest minimum size (as specified bymin-width
/min-height
) of the grid items occupying the grid track.
Formal syntax
minmax( min, max )
Example
CSS content
#container { display: grid; grid-template-columns: minmax(max-content, 300px) minmax(200px, 1fr) 150px; grid-gap: 5px; box-sizing: border-box; height: 200px; width: 100%; background-color: #8cffa0; padding: 10px; } #container > div { background-color: #8ca0ff; padding: 5px; }
HTML content
<div id="container"> <div> Item as wide as the content,<br/> but at most 300 pixels. </div> <div> Item with flexible width but a minimum of 200 pixels. </div> <div> Inflexible item of 150 pixels width. </div> </div>
