minmax()
Baseline: Widely supported
Baseline is determined by this web feature being supported on the current and the previous major versions of major browsers.
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.
Try it
Syntax
css
/* <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)
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 <flex>
value sets the flex factor of a grid track; it is invalid as a minimum.
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 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. <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.
