Bootstrap comes with several pre-defined colors for buttons. The `btn-danger` class is the button color you'll use to notify users that the button performs a destructive action, such as deleting a cat photo.

Create a button with the text `Delete` and give it the class `btn-danger` .
2020-11-27 18:02:05 +00:00
Note that these buttons still need the `btn` and `btn-block` classes.

You should create a new `button` element with the text `Delete` .
2020-11-27 18:02:05 +00:00
```js
assert(new RegExp('Delete', 'gi').test($('button').text()));
2018-09-30 22:01:58 +00:00
```

All of your Bootstrap buttons should have the `btn` and `btn-block` classes.
2018-09-30 22:01:58 +00:00
2020-11-27 18:02:05 +00:00
```js
assert($('button.btn-block.btn').length > 2);
```
Your new button should have the class `btn-danger` .
2018-09-30 22:01:58 +00:00
2020-11-27 18:02:05 +00:00
```js
assert($('button').hasClass('btn-danger'));
```
All of your `button` elements should have closing tags.
```js
assert(
code.match(/< \/button > /g) &&
code.match(/< button / g ) & &
code.match(/< \/button > /g).length === code.match(/< button / g ). length
);
```
