Step 6

Remember that a class attribute can have multiple values. To separate your white keys from your black keys, you’ll add a second class value of black--key. Add this to your second, third, fifth, sixth, and seventh .key elements.

This seems right to me… What am I missing?

Sorry, your code does not pass. Try again.

Your second .key element should also have a class of black--key.

Hello!

When you add another class value to the class you should add a space after your first class and then add your other value.
Example , here blue is the first class and green is the second class: <div class="blue green">
So remove your newly added class and add the value black--key in your original class.
