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);

/* <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];

/* Valores globais */
grid-template-rows: inherit;
grid-template-rows: initial;
grid-template-rows: unset;

Esta propriedade pode ser especificada como:

• com a palavra-chave none
• ou um valor <track-list> 
• ou um valor <auto-track-list> 

Valores

none

É uma palavra-chave que indica que não há uma grid explícita. Qualquer linha irá ser implicitamente gerada e seu tamanho será determinado pela a propriedade grid-auto-rows .

<length>

É um comprimento não negativo.

<percentagem>

É um valor de <percentagem> não negativo, relativo ao tamanho do bloco do grid contêiner. Se o tamanho do grid contêiner depender do tamanho de suas tracks, então a percentagem deve ser tratada como auto. 
As contribuições de tamanho inerentes da track podem ser ajustados ao tamanho do grid contêiner, e aumentar o tamanho final da track pelo o valor mínimo que respeitará a percentagem.

<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> | 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>
