The grid property in CSS

 Use grid-column to Control Spacing

Up to this point, all the properties that have been discussed are for grid containers. The grid-column property is the first one for use on the grid items themselves.

The hypothetical horizontal and vertical lines that create the grid are referred to as lines. These lines are numbered starting with 1 at the top left corner of the grid and move right for columns and down for rows, counting upward.

This is what the lines look like for a 3x3 grid:

column lines

1

2

3

4

row lines

1

2

3

4

To control the number of columns an item will consume, you can use the grid-column property in conjunction with the line numbers you want the item to start and stop at.

Here's an example:

grid-column: 1 / 3;

This will make the item start at the first vertical line of the grid on the left and span to the 3rd line of the grid, consuming two columns.

Use grid-row to Control Spacing

Of course, you can make items consume multiple rows just like you can with columns. You define the horizontal lines you want an item to start and stop at using the grid-row property on a grid item.
