# --description--

You can also target elements by their id attributes.

First target your `button` element with the id `target3` by using the `$("#target3")` selector.

Note that, just like with CSS declarations, you type a `#` before the id's name.

Then use jQuery's `.addClass()` function to add the classes `animated` and `fadeOut`.

Here's how you'd make the `button` element with the id `target6` fade out:

`$("#target6").addClass("animated fadeOut")`.

# --hints--

You should select the `button` element with the `id` of `target3` and use the jQuery `addClass()` function to give it the class of `animated`.

```js
assert($('#target3').hasClass('animated'));
```

You should target the element with the id `target3` and use the jQuery `addClass()` function to give it the class `fadeOut`.

```js
assert(
  ($('#target3').hasClass('fadeOut') || $('#target3').hasClass('fadeout')) &&
    code.match(/\$\(\s*.#target3.\s*\)/g)
);
```

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

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