Challenge: Step 6

Link to the challenge:

You just need to make sure that the children elements inside the main elements are indented by two spaces, and the main elements are only indented by 4 spaces from the left. You might need to restart the lesson, and then add 2 spaces to each child element (don’t touch the main elements) to pass this lesson.
