# --description--

Not every class needs to have corresponding CSS. Sometimes we create classes just for the purpose of selecting these elements more easily using jQuery.

Give each of your `button` elements the class `target`.

# --hints--

You should apply the `target` class to each of your `button` elements.

```js
assert($('.target').length > 5);
```
