# --description--
|
|
|
|
I don't like how spaced out the buildings are. Squeeze them together by adding two empty `div` elements to the top of the `background-buildings` element, two more at the bottom of it, and one more in between `.bb3` and `.bb4`. These will be added as evenly-spaced elements across the container, effectively moving the buildings closer to the center.
|
|
|
|
# --hints--
|
|
|
|
You should add two new `div` elements before the `.bb1` element.
|
|
|
|
```js
|
|
const bBuildings = document.querySelector('.background-buildings')?.children;
|
|
assert(![...bBuildings?.[0]?.classList]?.includes('bb1'));
|
|
assert(![...bBuildings?.[1]?.classList]?.includes('bb1'));
|
|
```
|
|
|
|
You should add one new `div` element between the `.bb3` and `.bb4` element.
|
|
|
|
```js
|
|
assert(document.querySelector('.bb3')?.nextElementSibling === document.querySelector('.bb4')?.previousElementSibling);
|
|
```
|
|
|
|
You should add two new `div` elements after the `.bb4` element.
|
|
|
|
```js
|
|
const bb4 = document.querySelector('.bb4');
|
|
assert.exists(bb4?.nextElementSibling);
|
|
assert.exists(bb4?.nextElementSibling?.nextElementSibling);
|
|
```
|
|
|
|
You should add 5 new `div` elements.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('div')?.length, 14);
|
|
```
