The grid-column CSS property is a shorthand property for grid-column-start 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 inline-start and inline-end edge of its grid area.

/* Keyword values */
grid-column: auto;
grid-column: auto / auto;

/* <custom-ident> values */
grid-column: somegridarea;
grid-column: somegridarea / someothergridarea;

/* <integer> + <custom-ident> values */
grid-column: somegridarea 4;
grid-column: 4 somegridarea / 6;

/* span + <integer> + <custom-ident> values */
grid-column: span 3;
grid-column: span somegridarea;
grid-column: 5 somegridarea span;
grid-column: span 3 / 6;
grid-column: span somegridarea / span someothergridarea;
grid-column: 5 somegridarea span / 2 span;

/* Global values */
grid-column: inherit;
grid-column: initial;
grid-column: unset;

If two <grid-line> values are specified, 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.

Syntax

This property is specified as one or two <grid-line> values. If two <grid-line> values are given they are separated by "/".

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.

Formal syntax

<grid-line> [ / <grid-line> ]?

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

Example

HTML Content

<div id="grid">
  <div id="item1"></div>
  <div id="item2"></div>
  <div id="item3"></div>
</div>

CSS Content

#grid {
  display: grid;
  height: 100px;
  grid-template-columns: repeat(6, 1fr);
  grid-template-rows: 100px;
}

#item1 {
  background-color: lime;
}

#item2 {
  background-color: yellow;
  grid-column: 2 / 4;
}

#item3 {
  background-color: blue;
  grid-column: span 2 / 7;
}

[2] Implemented behind the preference layout.css.grid.enabled since Gecko 40.0 (Firefox 40.0 / Thunderbird 40.0 / SeaMonkey 2.37), defaulting to false. Since Gecko 52.0 (Firefox 52.0 / Thunderbird 52.0 / SeaMonkey 2.49) it is enabled by default.

[3] Internet Explorer implements an older version of the specification, which only defines the related grid-cell and grid-column-span properties and is using the -ms prefix. Therefore part of the property is implemented there as -ms-grid-cell and -ms-grid-column-span, respectively.
