Синтаксис

Функция принимает два параметра, min и max.

Каждый параметр может быть значением <length>, либо <percentage>, либо <flex>, или одним из ключевых слов max-content, min-content, или auto.

Если max < min, то max игнорируется и minmax(min,max) обрабатывается как min. As a maximum, a <flex> value sets the flex factor of a grid track; it is invalid as a minimum.

Значения

<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 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>

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 by min-width/min-height) of the grid items occupying the grid track.

Формальный синтаксис

<minmax()> = 
  minmax( min , max )
