This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.


The grid-row-end CSS property specifies a grid item’s end position within the grid row by contributing a line, a span, or nothing (automatic) to its grid placement, thereby specifying the inline-end edge of its grid area.

/* <integer> + <custom-ident> values */
grid-row-end: 2;
grid-row-end: somegridarea 4;

grid-row-end: unset;


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.
If there is a named line with the name '<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-row-end: foo; will choose the end edge of that named grid area (unless another line named foo-end was explicitly specified before it).

Otherwise, this is treated as if the integer 1 had been specified along with the <custom-ident>.

The <custom-ident> cannot take the span value.

<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 row end edge of the grid item’s grid area is n lines from the start 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> = auto | <custom-ident> | [ <integer> && <custom-ident>? ] | [ span && [ <integer> || <custom-ident> ] ]

[1] Implemented behind the experimental Web Platform features flag in chrome://flags since Chrome 29.0.

[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 a grid-cell and a grid-row-span property, and is using the -ms prefix. Therefore part of the property is implemented there as -ms-grid-cell and -ms-grid-row-span, respectively.

[4] Implemented behind the Enable experimental Web Platform features flag in chrome://flags since Opera 28.0.
