The grid-template-rows CSS property defines the line names and track sizing functions of the grid rows.

Try it

grid-template-rows: auto;

grid-template-rows: 40px 4em 40px;

grid-template-rows: 1fr 2fr 1fr;

grid-template-rows: 3ch auto minmax(10px, 60px);

<section class="default-example" id="default-example">
  <div class="example-container">

      <div>One</div>
      <div>Two</div>
      <div>Three</div>
      <div>Four</div>
      <div>Five</div>
    </div>
  </div>
</section>

#example-element {

This property may be specified as:

• either the keyword value none
• or a <track-list> value
• or an <auto-track-list> value.

Values

none

A keyword meaning that there is no explicit grid. Any rows will be implicitly generated and their size will be determined by the grid-auto-rows property.

[line-name]

A <custom-ident> specifying a name for the line in that location. The ident may be any valid string other than the reserved words span and auto. Lines may have multiple names separated by a space inside the square brackets, for example [line-name-a line-name-b].

<length>

A non-negative length.

<percentage>

A non-negative <percentage> value, relative to the block size of the grid container. If the size of the grid container depends on the size of its tracks, the browser treats the percentage as auto for the purpose of calculating the intrinsic size of the grid container. The percentage is then resolved against the resulting grid container size for laying out the grid and its items. The browser may adjust the intrinsic size contributions of the track to the size of the grid container and may increase the final size of the track by the minimum amount that would result in honoring the percentage.

<flex>

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

A keyword representing the largest maximal content contribution of the grid items occupying the grid track.

min-content

A keyword representing the largest minimal content contribution of the grid items occupying the grid track.

minmax(min, max)

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. It is invalid as a minimum.

auto

As a maximum value, it represents the largest max-content size of the items in that track.

As a minimum value, it represents the largest minimum size of items in that track (specified by the min-width/min-height properties of the items). This often corresponds to the min-content size, but not always.

If used outside of minmax() notation, auto represents the range between the minimum and maximum values described above. In most cases, this behaves similarly to minmax(min-content,max-content).

Note: auto track sizes (and only auto track sizes) can be stretched by the align-content and justify-content properties. Therefore, by default, an auto-sized track will take up any remaining space in the grid container.

fit-content( [ <length> | <percentage> ] )

Represents the formula min(max-content, max(auto, argument)), which is calculated similar to auto (i.e., minmax(auto, max-content)), except that the track size is clamped at argument if it is greater than the auto minimum.

repeat( [ <positive-integer> | auto-fill | auto-fit ] , <track-list> )

Represents a repeated fragment of the track list, allowing a large number of rows that exhibit a recurring pattern to be written in a more compact form.

masonry

Indicates that this axis should be laid out according to the masonry algorithm.

subgrid

Indicates that the grid will adopt the spanned portion of its parent grid in that axis. Rather than being specified explicitly, the sizes of the grid rows/columns will be taken from the parent grid's definition.
