grid-template-rows

The grid-template-rows CSS property defines the line names and track sizing functions of the grid rows.

Syntax

/* Keyword value */
grid-template-rows: none;

/* <track-list> values */
grid-template-rows: 100px 1fr;
grid-template-rows: [linename] 100px;
grid-template-rows: [linename1] 100px [linename2 linename3];
grid-template-rows: minmax(100px, 1fr);
grid-template-rows: fit-content(40%);
grid-template-rows: repeat(3, 200px);
grid-template-rows: subgrid;
grid-template-rows: masonry;

/* <auto-track-list> values */
grid-template-rows: 200px repeat(auto-fill, 100px) 300px;
grid-template-rows: minmax(100px, max-content)
                       repeat(auto-fill, 200px) 20%;
grid-template-rows: [linename1] 100px [linename2]
                       repeat(auto-fit, [linename3 linename4] 300px)
                       100px;
grid-template-rows: [linename1 linename2] 100px
                       repeat(auto-fit, [linename1] 300px) [linename3];

/* Global values */
grid-template-rows: inherit;
grid-template-rows: initial;
grid-template-rows: unset;

This property may be specified as:

  • either the keyword value none
  • or a <track-list> value
  • or an <auto-track-list> value.

Values

none
Is a keyword meaning that there is no explicit grid. Any rows will be implicitly generated and their size will be determined by the grid-auto-rows property.
[linename]
A <custom-ident> specifying a name for the line in that location. The ident may be any valid string other then the reserved words span and auto. Lines may have multiple names separated by a space inside the square brackets, for example [line-name-a line-name-b].
<length>
Is a non-negative length.
<percentage>
Is a non-negative <percentage> value, relative to the block size of the grid container. If the size of the grid container depends on the size of its tracks, then the percentage must be treated as auto.
The intrinsic size contributions of the track may be adjusted 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>
Is 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. When appearing outside a minmax() notation, it implies an automatic minimum (i.e. minmax(auto, <flex>)).
max-content
Is a keyword representing the largest maximal content contribution of the grid items occupying the grid track.
min-content
Is a keyword representing the largest minimal content contribution of the grid items occupying the grid track.
minmax(min, max)
Is a functional notation that defines a size range, greater than or equal to min, and less than or equal to max. If max is smaller than min, then max is ignored and the function is treated as min. As a maximum, a <flex> value sets the track’s flex factor. It is invalid as a minimum.
auto
Is a keyword that is identical to maximal content if it's a maximum. As a minimum it represents the largest minimum size (as specified by min-width/min-height) of the grid items occupying the grid track.

Note: auto track sizes (and only auto track sizes) can be stretched by the align-content and justify-content properties.

fit-content( [ <length> | <percentage> ] )
Represents the formula min(max-content, max(auto, argument)), which is calculated similar to auto (i.e. minmax(auto, max-content)), except that the track size is clamped at argument if it is greater than the auto minimum.
repeat( [ <positive-integer> | auto-fill | auto-fit ] , <track-list> )
Represents a repeated fragment of the track list, allowing a large number of rows that exhibit a recurring pattern to be written in a more compact form.
masonry
The masonry value indicates that this axis should be laid out according to the masonry algorithm.
subgrid
The subgrid value indicates that the grid will adopt the spanned portion of its parent grid in that axis. Rather than being specified explicitly, the sizes of the grid rows/columns will be taken from the parent grid’s definition.

The masonry value is from Level 3 of the Grid specification and currently only has an experimental implementation behind a flag in Firefox.

The subgrid value is from Level 2 of the Grid specification and currently only has implementation in Firefox 71 and onwards.

Formal definition

Initial value none
Applies to grid containers
Inherited no
Percentages refer to corresponding dimension of the content area
Computed value as specified, but with relative lengths converted into absolute lengths
Animation type simple list of length, percentage, or calc, provided the only differences are in the values of the length, percentage, or calc components in the list

Formal syntax

none | <track-list> | <auto-track-list> | subgrid <line-name-list>?

where
<track-list> = [ <line-names>? [ <track-size> | <track-repeat> ] ]+ <line-names>?
<auto-track-list> = [ <line-names>? [ <fixed-size> | <fixed-repeat> ] ]* <line-names>? <auto-repeat> [ <line-names>? [ <fixed-size> | <fixed-repeat> ] ]* <line-names>?
<line-name-list> = [ <line-names> | <name-repeat> ]+

where
<line-names> = '[' <custom-ident>* ']'
<track-size> = <track-breadth> | minmax( <inflexible-breadth> , <track-breadth> ) | fit-content( [ <length> | <percentage> ] )
<track-repeat> = repeat( [ <positive-integer> ] , [ <line-names>? <track-size> ]+ <line-names>? )
<fixed-size> = <fixed-breadth> | minmax( <fixed-breadth> , <track-breadth> ) | minmax( <inflexible-breadth> , <fixed-breadth> )
<fixed-repeat> = repeat( [ <positive-integer> ] , [ <line-names>? <fixed-size> ]+ <line-names>? )
<auto-repeat> = repeat( [ auto-fill | auto-fit ] , [ <line-names>? <fixed-size> ]+ <line-names>? )

where
<track-breadth> = <length-percentage> | <flex> | min-content | max-content | auto
<inflexible-breadth> = <length> | <percentage> | min-content | max-content | auto
<fixed-breadth> = <length-percentage>

where
<length-percentage> = <length> | <percentage>
