--description--

Now copy the set of seven .key elements, and paste two more sets into the .keys div.

--hints--

You should have 21 .key elements.

const keys = document.querySelectorAll('.key');
assert(keys?.length === 21);

You should have 15 .black--key elements.

const blackKeys = document.querySelectorAll('.black--key');
assert(blackKeys?.length === 15);

All .key elements should be within your .keys element.

const keys = document.querySelector('.keys');
assert(keys?.querySelectorAll('.key')?.length === 21);

All .black--key elements should be within your .keys element.

const keys = document.querySelector('.keys');
assert(keys?.querySelectorAll('.black--key')?.length === 15);
