# --description--
|
|
|
|
Nest a second `div` within your existing `div`, and set the `class` to be `keys`.
|
|
|
|
# --hints--
|
|
|
|
You should create a second `div` element.
|
|
|
|
```js
|
|
const divDiv = document.querySelectorAll('div');
|
|
assert(divDiv?.length === 2);
|
|
```
|
|
|
|
Your new `div` element should be within your existing `div` element.
|
|
|
|
```js
|
|
const div = document.querySelector('div');
|
|
assert(div?.children?.length === 1);
|
|
assert(div?.children?.[0]?.localName === 'div');
|
|
```
|
|
|
|
Your new `div` element should have the `class` set to `keys`.
|
|
|
|
```js
|
|
const div = document.querySelector('div');
|
|
assert(div?.children?.[0]?.className === 'keys');
|
|
```
