# --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));
|
|
```
