| # --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:
 | |
| 
 | |
| ```js
 | |
| $("#target6").addClass("animated fadeOut");
 | |
| ```
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| You should select the `button` element with the `id` of `target3` and use the jQuery `addClass()` function to give it the class of `animated`.
 | |
| 
 | |
| ```js
 | |
| assert($('#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));
 | |
| ```
