--description--

Nest four div elements in the .bb1 container. Give them the classes bb1a, bb1b, bb1c, and bb1d in that order. This building will have four sections.

--hints--

You should create four new div elements.

js
assert.equal(document.querySelectorAll('div')?.length, 6);

You should give one of the new div elements a class of bb1a.

js
assert.exists(document.querySelector('div.bb1a'));

You should give one of the new div elements a class of bb1b.

js
assert.exists(document.querySelector('div.bb1b'));

You should give one of the new div elements a class of bb1c.

js
assert.exists(document.querySelector('div.bb1c'));

You should give one of the new div elements a class of bb1d.

js
assert.exists(document.querySelector('div.bb1d'));

You should place the new div elements in the correct order.

js
function __t(a, b) {
  return [...document.querySelector(a)?.nextElementSibling?.classList]?.includes(b);
}
assert.isTrue(__t('div.bb1a','bb1b') && __t('div.bb1b','bb1c') && __t('div.bb1c','bb1d'));

You should place the new div elements within the .bb1 element.

js
assert.equal(document.querySelectorAll('div.bb1 > div')?.length, 4);
