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

/* 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);

/* <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];

Syntax

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.
<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.

Formal syntax

none | <track-list> | <auto-track-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>?

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>

Examples

#areaB {
  background-color: yellow;
}

HTML

<div id="grid">
  <div id="areaA">A</div>
