The grid-auto-columns property in CSS is used to specify the size of the columns of implicitly generated grid containers.
Syntax:
grid-auto-columns: auto|max-content|min-content|length|
percentage|minmax(min, max)|initial|inherit;
Property Values:
- auto: It is the default value. The size is determined implicitly according to the size of the container.
- length: It is used to specify the size as an integer length. Negative values are not allowed.
- percentage: It specifies the size as a percentage value.
- max-content: It specifies the size depending on the largest item in the container.
- min-content: It specifies the size depending on the smallest item in the container.
- minmax(min, max): It specifies the size in the range of [min, max]. greater than or equal to min and less than or equal to max.
- initial: It sets the grid-auto-columns property to its default value.
- inherit: It sets the grid-auto-columns property from its parent element.
