--- id: 5d822fd413a79914d39e98e6 title: Step 30 challengeType: 0 dashedName: step-30 --- # --description-- Annida 6 elementi `div` all'interno di `.foreground-buildings` e assegna loro le classi da `fb1` a `fb6` in ordine. "fb" sta per "foreground building". Saranno altri sei edifici in primo piano. # --hints-- Dovresti creare un nuovo `div` con la classe `fb1`. ```js assert.exists(document.querySelector('div.fb1')); ``` Dovresti creare un nuovo `div` con la classe `fb2`. ```js assert.exists(document.querySelector('div.fb2')); ``` Dovresti creare un nuovo `div` con la classe `fb3`. ```js assert.exists(document.querySelector('div.fb3')); ``` Dovresti creare un nuovo `div` con la classe `fb4`. ```js assert.exists(document.querySelector('div.fb4')); ``` Dovresti creare un nuovo `div` con la classe `fb5`. ```js assert.exists(document.querySelector('div.fb5')); ``` Dovresti creare un nuovo `div` con la classe `fb6`. ```js assert.exists(document.querySelector('div.fb6')); ``` Dovresti inserire i nuovi elementi `div` all'interno dell'elemento `.foreground-buildings`. ```js assert.exists(document.querySelector('div.foreground-buildings > div.fb1')); assert.exists(document.querySelector('div.foreground-buildings > div.fb2')); assert.exists(document.querySelector('div.foreground-buildings > div.fb3')); assert.exists(document.querySelector('div.foreground-buildings > div.fb4')); assert.exists(document.querySelector('div.foreground-buildings > div.fb5')); assert.exists(document.querySelector('div.foreground-buildings > div.fb6')); ``` Dovresti inserire i nuovi elementi `div` nell'ordine corretto. ```js function __t(a, b) { return [...document.querySelector(a)?.nextElementSibling?.classList]?.includes(b); } assert(__t('div.fb1','fb2') && __t('div.fb2','fb3') && __t('div.fb3','fb4') && __t('div.fb4', 'fb5') && __t('div.fb5', 'fb6')); ``` # --seed-- ## --seed-contents-- ```html City Skyline
