Generic font family names are not case-sensitive. Also, they do not need quotes because they are CSS keywords.

Because of cascading, CSS variables are often defined in the :root element.

:root {

--penguin-belly: pink;

}

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:

To control the amount 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.
