--description--

Comprimi di nuovo gli edifici aggiungendo due elementi div vuoti sia in cima che alla fine dell'elemento .foreground-buildings e uno tra .fb2 e .fb3.

--hints--

Dovresti aggiungere due elementi div come primi figli di .foreground-buildings.

const bBuildings = document.querySelector('.background-buildings')?.children;
assert(![...bBuildings?.[0]?.classList]?.includes('fb1'));
assert(![...bBuildings?.[1]?.classList]?.includes('fb1'));

Dovresti aggiungere un nuovo elemento div tra l'elemento .fb2 e .fb3.

assert(document.querySelector('.fb2')?.nextElementSibling === document.querySelector('.fb3')?.previousElementSibling);

Dovresti aggiungere due elementi div come ultimi figli di .foreground-buildings.

const fb6 = document.querySelector('.fb6');
assert.exists(fb6?.nextElementSibling);
assert.exists(fb6?.nextElementSibling?.nextElementSibling);

Dovresti aggiungere 5 nuovi elementi div.

assert.equal(document.querySelectorAll('div')?.length, 26);
