# --description--
|
|
|
|
Your first building looks pretty good now. Let's make some more! Nest three new `div` elements in the `background-buildings` container and give them the classes of `bb2`, `bb3`, and `bb4` in that order. These will be three more buildings for the background.
|
|
|
|
# --hints--
|
|
|
|
You should create a `div` with a class of `bb2`.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb2'));
|
|
```
|
|
|
|
You should create a `div` with a class of `bb3`.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb3'));
|
|
```
|
|
|
|
You should create a `div` with a class of `bb4`.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb4'));
|
|
```
|
|
|
|
You should create 3 new `div` elements.
|
|
|
|
```js
|
|
assert.equal(document.querySelectorAll('div')?.length, 9);
|
|
```
|
|
|
|
You should place these `div` elements within the `.background-buildings` element.
|
|
|
|
```js
|
|
assert.equal(document.querySelector('div.background-buildings')?.children?.length, 4);
|
|
```
|
|
|
|
You should place the elements in the correct order.
|
|
|
|
```js
|
|
function __t(a, b) {
|
|
return [...document.querySelector(a)?.nextElementSibling?.classList]?.includes(b);
|
|
}
|
|
assert(__t('div.bb1','bb2') && __t('div.bb2','bb3') && __t('div.bb3','bb4'));
|
|
```
