| Value | Description |
|---|---|
| length | A non-negative length. |
| percentage | A non-negative percentage relative to the inline size of the grid container in column grid tracks, and the block size of the grid container in row grid tracks. If the size of the grid container depends on the size of its tracks, then percentage must be treated as auto. The user agent may adjust the intrinsic size contributions of the track to the size of the grid container and 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 fr unit that specifies the flex factor of the grid track. Tracks sized with flex cause the track to become flexible and consume the remaining space proportional to their flex factor. |
| max-content | Represents the largest maximal content contribution of the grid items occupying the grid track. |
| min-content | Represents the largest minimal content contribution of the grid items occupying the grid track. |
| auto | As a maximum, identical to max-content. As a minimum, represents the largest minimum size (as specified by min-width/min-height) of the grid items occupying the grid track. |
