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 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
.
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 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
- 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.
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 |
