Use grid-column to Control Spacing (Column Count)

Hello Campers,

On the CSS Grid: Use grid-column to Control Spacing exercise it asks to " Make the item with the class item5 consume the last two columns of the grid."

For me the last two columns are 3 and 4. So how come the answer is:

Spoiler Alert

grid-column: 2 / 4;


Hello there.

Going back to the picture:
You want to consume the area between column line 2 and column line 4.
grid-column: 2 / 4;

Hope this helps

Thank you so much for your help!
