grid-template-rows
Baseline: Widely supported
Baseline is determined by this web feature being supported on the current and the previous major versions of major browsers.
The grid-template-rows
CSS property defines the line names and track sizing functions of the grid rows.

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 than the reserved wordsspan
andauto
. 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 asauto
for the purpose of calculating the intrinsic size of the grid container. It must then be resolved against the resulting grid container size for the purpose of laying out the grid and its items. The intrinsic size contributions of the track may be adjusted to the size of the grid container and may 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 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 track's flex factor. It is invalid as a minimum. auto
-
As a maximum represents the largest
max-content
size of the items in that track.As a minimum represents the largest minimum size of items in that track (specified by the
min-width
/min-height
of the items). This is often, though not always, themin-content
size.If used outside of
minmax()
notation,auto
represents the range between the minimum and maximum described above. This behaves similarly tominmax(min-content,max-content)
in most cases.Note:
auto
track sizes (and onlyauto
track sizes) can be stretched by thealign-content
andjustify-content
properties. Therefore by default, anauto
sized track will take up any remaining space in the grid container. 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.
masonry
Experimental-
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.
Warning: 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 |
