The grid-column CSS shorthand property specifies a grid item's size and location within a grid column by contributing a line, a span, or nothing (automatic) to its grid placement, thereby specifying the inline-start and inline-end edge of its grid area.

grid-column: auto;  /* with line numbers */ grid-column: 1; grid-column: 1 / 3; grid-column: 1 /  span 2;  /* with line names */ grid-column: main-start; grid-column: main-start / main-end;  /* Global values */ grid-column: inherit; grid-column: initial; grid-column: revert; grid-column: unset; 

grid-column

The grid-column CSS shorthand property specifies a grid item's size and location within a grid column by contributing a line, a span, or nothing (automatic) to its grid placement, thereby specifying the inline-start and inline-end edge of its grid area.

Constituent properties

This property is a shorthand for the following CSS properties:

grid-column-end grid-column-start

Syntax

grid-column: auto;  /* with line numbers */ grid-column: 1; grid-column: 1 / 3; grid-column: 1 /  span 2;  /* with line names */ grid-column: main-start; grid-column: main-start / main-end;  /* Global values */ grid-column: inherit; grid-column: initial; grid-column: revert; grid-column: unset; 

This property is specified as one or two <grid-line> values.

If two <grid-line> values are given they are separated by "/". The grid-column-start longhand is set to the value before the slash, and the grid-column-end longhand is set to the value after the slash.

Each <grid-line> value can be specified as:

either the auto keyword or a <custom-ident> value or an <integer> value or both <custom-ident> and <integer>, separated by a space or the keyword span together with either a <custom-ident> or an <integer> or both.

Values

auto

Is a keyword indicating that the property contributes nothing to the grid item's placement, indicating auto-placement, an automatic span, 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-column: 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.
