Challenge: Step 30

Link to the challenge:

Just swap position of your margin and margin-top properties and you should be able to progress.

margin-top is auto becase, margin is to assign a value to all directions, and the lower property wins

To touch on this a little, this is because the code is read from top to bottom so it is initially reading your code as margin-top: 65% then it is overwriting it to be margin: auto instead. Hence why swapping the positions works as intended.
