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; /* <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. <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 asauto
.
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 trackโs flex factor. Each<flex>
-sized track takes a share of the remaining space in proportion to its flex factor. When appearing outside aminmax()
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 trackโs 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 onlyauto
track sizes) can be stretched by thealign-content
andjustify-content
properties. fit-content( [ <length> | <percentage> ] )
- Represents the formula
min(max-content, max(auto, argument))
, which is calculated similar toauto
(i.e.minmax(auto, max-content)
), except that the track size is clamped at argument if it is greater than theauto
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.
- 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 gridโs definition.
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>
Examples
Specifying grid row sizes
HTML
<div id="grid"> <div id="areaA">A</div> <div id="areaB">B</div> </div>
CSS
#grid { display: grid; height: 100px; grid-template-rows: 30px 1fr; } #areaA { background-color: lime; } #areaB { background-color: yellow; }
