grid-area

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.

/* 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;

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.

Initial value as each of the properties of the shorthand:
Applies to grid items and absolutely-positioned boxes whose containing block is a grid container
Inherited no
Media visual
Computed value as each of the properties of the shorthand:
Animation type discrete
Canonical order the unique non-ambiguous order defined by the formal grammar

Syntax

Values

auto
Is a keyword indicating that the property contributes nothing to the grid item’s placement, indicating auto-placement or a default span of 1.
<custom-ident>
If there is a named line with the name '<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>?
Contributes the nth grid line to the grid item’s placement. If a negative integer is given, it instead counts in reverse, starting from the end edge of the explicit grid.

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> ]
Contributes a grid span to the grid item’s placement such that the corresponding edge of the grid item’s grid area is n lines from the opposite edge.

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.

Formal syntax

<grid-line> [ / <grid-line> ]{0,3}

where
<grid-line> = auto | <custom-ident> | [ <integer> && <custom-ident>? ] | [ span && [ <integer> || <custom-ident> ] ]

Example

HTML content
