# --description--
|
|
|
|
Add the new `bb1-window` class to the `.bb1a`, `.bb1b`, and `.bb1c` elements. This will apply the gradient to them.
|
|
|
|
# --hints--
|
|
|
|
You should not remove the `bb1a` class.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1a'));
|
|
```
|
|
|
|
You should add the `bb1-window` class to the `.bb1a` element.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1a.bb1-window'));
|
|
```
|
|
|
|
You should not remove the `bb1b` class.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1b'));
|
|
```
|
|
|
|
You should add the `bb1-window` class to the `.bb1b` element.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1b.bb1-window'));
|
|
```
|
|
|
|
You should not remove the `bb1c` class.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1c'));
|
|
```
|
|
|
|
You should add the `bb1-window` class to the `.bb1c` element.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1c.bb1-window'));
|
|
```
|
|
|
|
You should not change the `.bb1d` element.
|
|
|
|
```js
|
|
assert.exists(document.querySelector('div.bb1d'));
|
|
assert.notExists(document.querySelector('div.bb1d.bb1-window'));
|
|
```
