The grid-auto-rows
CSS property specifies the size of an implicitly-created grid row track.
/* Keyword values */ grid-auto-rows: min-content; grid-auto-rows: max-content; grid-auto-rows: auto; /* <length> values */ grid-auto-rows: 100px; grid-auto-rows: 20cm; grid-auto-rows: 50vmax; /* <percentage> values */ grid-auto-rows: 10%; grid-auto-rows: 33.3%; /* <flex> values */ grid-auto-rows: 0.5fr; grid-auto-rows: 3fr; /* minmax() values */ grid-auto-rows: minmax(100px, auto); grid-auto-rows: minmax(max-content, 2fr); grid-auto-rows: minmax(20%, 80vmax); /* multiple track-size values */ grid-auto-rows: min-content max-content auto; grid-auto-rows: 100px 150px 390px; grid-auto-rows: 10% 33.3%; grid-auto-rows: 0.5fr 3fr 1fr; grid-auto-rows: minmax(100px, auto) minmax(max-content, 2fr) minmax(20%, 80vmax); grid-auto-rows: 100px minmax(100px, auto) 10% 0.5fr fit-content(400px); /* Global values */ grid-auto-rows: inherit; grid-auto-rows: initial; grid-auto-rows: unset;
If a grid item is positioned into a row that is not explicitly sized by grid-template-rows
, implicit grid tracks are created to hold it. This can happen either by explicitly positioning into a row that is out of range, or by the auto-placement algorithm creating additional rows.

Syntax
Values
<length>
- Is a non-negative length.
<percentage>
- Is a non-negative
<percentage>
value relative to the block size of the grid container. If the block size of the grid container is indefinite, the percentage value is treated likeauto
. <flex>
- Is a non-negative dimension with the unit
fr
specifying the track’s flex factor. Each<flex>
-sized track takes a share of the remaining space in proportion to its flex factor.When appearing outside a
minmax()
notation, it implies an automatic minimum (i.e.minmax(auto, <flex>)
). max-content
- Is a keyword representing the largest maximal content contribution of the grid items occupying the grid track.
min-content
- Is a keyword representing the largest minimal content contribution of the grid items occupying the grid track.
minmax(min, max)
- Is a functional notation that defines a size range greater than or equal to min and less than or equal to max. If max is smaller than min, then max is ignored and the function is treated as min. As a maximum, a
<flex>
value sets the track’s flex factor. As a minimum, it is treated as zero (or minimal content, if the grid container is sized under a minimal content constraint). auto
- Is a keyword that is identical to maximal content if it's a maximum. As a minimum it represents the largest minimum size (as specified by
min-width
/min-height
) of the grid items occupying the grid track. -
Note:
auto
track sizes (and onlyauto
track sizes) can be streched by thealign-content
andjustify-content
properties.
Formal syntax
<track-size>+where
<track-size> = <track-breadth> | minmax( <inflexible-breadth> , <track-breadth> ) | fit-content( [ <length> | <percentage> ] )
where
<track-breadth> = <length-percentage> | <flex> | min-content | max-content | auto
<inflexible-breadth> = <length> | <percentage> | min-content | max-content | autowhere
<length-percentage> = <length> | <percentage>
Example
HTML Content
<div id="grid"> <div id="item1"></div> <div id="item2"></div> <div id="item3"></div> </div>
CSS Content
#grid { width: 200px; display: grid; grid-template-areas: "a a"; grid-gap: 10px; grid-auto-rows: 100px; } #grid > div { background-color: lime; }
