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.
/* <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.
<length>
<percentage>
<percentage>
must be treated as auto
. 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>
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
min-content
auto
max-content
. As a minimum it represents the largest minimum size (as specified by min-width
/min-height
) of the grid items occupying the grid track.minmax( [ <length> | <percentage> | <flex> | min-content | max-content | auto ] , [ <length> | <percentage> | <flex> | min-content | max-content | auto ] )
minmax()
function can be used within:
#container { display: grid; grid-template-columns: minmax(min-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; }
<div id="container"> <div> Item as wide as the content, 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>
