# --description--
|
|
|
|
You see how we made all of your `button` elements bounce? We selected them with `$("button")`, then we added some CSS classes to them with `.addClass("animated bounce");`.
|
|
|
|
You just used jQuery's `.addClass()` function, which allows you to add classes to elements.
|
|
|
|
First, let's target your `div` elements with the class `well` by using the `$(".well")` selector.
|
|
|
|
Note that, just like with CSS declarations, you type a `.` before the class's name.
|
|
|
|
Then use jQuery's `.addClass()` function to add the classes `animated` and `shake`.
|
|
|
|
For example, you could make all the elements with the class `text-primary` shake by adding the following to your `document ready function`:
|
|
|
|
`$(".text-primary").addClass("animated shake");`
|
|
|
|
# --hints--
|
|
|
|
You should use the jQuery `addClass()` function to give the classes `animated` and `shake` to all your elements with the class `well`.
|
|
|
|
```js
|
|
assert($('.well').hasClass('animated') && $('.well').hasClass('shake'));
|
|
```
|
|
|
|
You should only use jQuery to add these classes to the element.
|
|
|
|
```js
|
|
assert(!code.match(/class\.\*animated/g));
|
|
```
