# --description--

Now you know three ways of targeting elements: by type: `$("button")`, by class: `$(".btn")`, and by id `$("#target1")`.

Although it is possible to add multiple classes in a single `.addClass()` call, let's add them to the same element in *three separate ways*.

Using `.addClass()`, add only one class at a time to the same element, three different ways:

Add the `animated` class to all elements with type `button`.

Add the `shake` class to all the buttons with class `.btn`.

Add the `btn-primary` class to the button with id `#target1`.

**Note:** You should only be targeting one element and adding only one class at a time. Altogether, your three individual selectors will end up adding the three classes `shake`, `animated`, and `btn-primary` to `#target1`.

# --hints--

Your code should use the `$("button")` selector.

```js
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?button\s*?(?:'|")/gi));
```

Your code should use the `$(".btn")` selector.

```js
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?\.btn\s*?(?:'|")/gi));
```

Your code should use the `$("#target1")` selector.

```js
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")/gi));
```

You should only add one class with each of your three selectors.

```js
assert(
  code.match(/addClass/g) &&
    code.match(/addClass\s*?\(\s*?('|")\s*?[\w-]+\s*?\1\s*?\)/g).length > 2
);
```

Your `#target1` element should have the classes `animated`‚ `shake` and `btn-primary`.

```js
assert(
  $('#target1').hasClass('animated') &&
    $('#target1').hasClass('shake') &&
    $('#target1').hasClass('btn-primary')
);
```

You should only use jQuery to add these classes to the element.

```js
assert(!code.match(/class.*animated/g));
```
