The grid-area
CSS property is a shorthand property for grid-row-start
, grid-column-start
, grid-row-end
and grid-column-end
, specifying a grid item’s size and location within the grid row by contributing a line, a span, or nothing (automatic) to its grid placement, thereby specifying the edges of its grid area.
If four <grid-line>
values are specified, grid-row-start
is set to the first value, grid-column-start
is set to the second value, grid-row-end
is set to the third value, and grid-column-end
is set to the fourth value.
When grid-column-end
is omitted, if grid-column-start
is a <custom-ident>
, grid-column-end
is set to that <custom-ident>
; otherwise, it is set to auto
.
When grid-row-end
is omitted, if grid-row-start
is a <custom-ident>
, grid-row-end
is set to that <custom-ident>
; otherwise, it is set to auto
.
When grid-column-start
is omitted, if grid-row-start
is a <custom-ident>
, all four longhands are set to that value. Otherwise, it is set to auto
.
The grid-area property can also be set to a <custom-ident>
which acts as a name for the area, which can then be placed using grid-template-areas
.
/* Keyword values */ grid-area: auto; grid-area: auto / auto; grid-area: auto / auto / auto; grid-area: auto / auto / auto / auto; /* <custom-ident> values */ grid-area: some-grid-area; grid-area: some-grid-area / another-grid-area; /* <integer> && <custom-ident>? values */ grid-area: some-grid-area 4; grid-area: some-grid-area 4 / 2 another-grid-area; /* span && [ <integer> || <custom-ident> ] values */ grid-area: span 3; grid-area: span 3 / span some-grid-area; grid-area: 2 span / another-grid-area span; /* Global values */ grid-area: inherit; grid-area: initial; grid-area: unset;
auto
1
.<custom-ident>
<custom-ident>-start
'/'<custom-ident>-end
', it contributes the first such line to the grid item’s placement. Note: Named grid areas automatically generate implicit named lines of this form, so specifying grid-area: foo;
will choose the start/end edge of that named grid area (unless another line named foo-start
/foo-end
was explicitly specified before it).
Otherwise, this is treated as if the integer 1
had been specified along with the <custom-ident>
.
<integer> && <custom-ident>?
If a name is given as a <custom-ident>
, only lines with that name are counted. If not enough lines with that name exist, all implicit grid lines are assumed to have that name for the purpose of finding this position.
An <integer>
value of 0
is invalid.
span && [ <integer> || <custom-ident> ]
If a name is given as a <custom-ident>
, only lines with that name are counted. If not enough lines with that name exist, all implicit grid lines on the side of the explicit grid corresponding to the search direction are assumed to have that name for the purpose of counting this span.
If the <integer>
is omitted, it defaults to 1
. Negative integers or 0 are invalid.
<grid-line> [ / <grid-line> ]{0,3}where
<grid-line> = auto | <custom-ident> | [ <integer> && <custom-ident>? ] | [ span && [ <integer> || <custom-ident> ] ]
<div id="grid"> <div id="item1"></div> <div id="item2"></div> <div id="item3"></div> </div>
#grid { display: grid; height: 100px; grid-template: repeat(4, 1fr) / 50px 100px; } #item1 { background-color: lime; grid-area: 2 / 2 / auto / span 3; } #item2 { background-color: yellow; } #item3 { background-color: blue; }
