Grid Column

A grid column is a vertical track in a CSS grid layout, and is the space between two vertical grid lines. It is defined by the grid-template-columns property or in the shorthand grid or grid-template properties.

In addition, columns may be created in the implicit grid when items are placed outside of columns created in the explicit grid. These columns will be auto-sized by default, or can have a size specified with the grid-auto-columns property.

When working with alignment in CSS grid layout, the axis down which columns run is known as the block, or column, axis.
