# --description--
Squeeze the buildings together again by adding two empty `div` elements within both the top and bottom of the `.foreground-buildings` element, and one more in between `.fb2` and `.fb3`.
# --hints--
You should add two `div` elements as the first children of `.foreground-buildings`.
```js
const bBuildings = document.querySelector('.background-buildings')?.children;
assert(![...bBuildings?.[0]?.classList]?.includes('fb1'));
assert(![...bBuildings?.[1]?.classList]?.includes('fb1'));
```
You should add one `div` element between `.fb2` and `.fb3`.
```js
assert(document.querySelector('.fb2')?.nextElementSibling === document.querySelector('.fb3')?.previousElementSibling);
```
You should add two `div` elements as the last children of `.foreground-buildings`.
```js
const fb6 = document.querySelector('.fb6');
assert.exists(fb6?.nextElementSibling);
assert.exists(fb6?.nextElementSibling?.nextElementSibling);
```
You should have added 5 new `div` elements.
```js
assert.equal(document.querySelectorAll('div')?.length, 26);
```
