"fb" stands for "foreground building". These will be six more buildings for the foreground. # --hints-- You should create a new `div` with a class of `fb1`. ```js assert.exists(document.querySelector('div.fb1')); ``` You should create a new `div` with a class of `fb2`. ```js assert.exists(document.querySelector('div.fb2')); ``` You should create a new `div` with a class of `fb3`. ```js assert.exists(document.querySelector('div.fb3')); ``` You should create a new `div` with a class of `fb4`. ```js assert.exists(document.querySelector('div.fb4')); ``` You should create a new `div` with a class of `fb5`. ```js assert.exists(document.querySelector('div.fb5')); ``` You should create a new `div` with a class of `fb6`. ```js assert.exists(document.querySelector('div.fb6')); ``` You should place these new `div` elements within the `.foreground-buildings` element. ```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')); ``` 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(__t('div.fb1','fb2') && __t('div.fb2','fb3') && __t('div.fb3','fb4') && __t('div.fb4', 'fb5') && __t('div.fb5', 'fb6')); ``` # --seed-- ## --seed-contents-- ```html
