¿Ves cómo hemos hecho que todos tus elementos `button` reboten? Los seleccionamos con `$("button")` , luego agregamos algo de clases CSS a ellos con `.addClass("animated bounce");` .

Acabas de usar la función `.addClass()` de jQuery, que te permite agregar clases a los elementos.

Primero, apuntemos tus elementos `div` con la clase `well` usando el selector `$(".well")` .

Ten en cuenta que, al igual que con las declaraciones CSS, escribes un `.` antes del nombre de la clase.

Luego usa la función `.addClass()` de jQuery para agregar las clases `animated` y `shake` .

Por ejemplo, puedes hacer que todos los elementos con la clase `text-primary` se agiten agregando lo siguiente a tu función `document ready function` :
2021-02-06 04:42:36 +00:00
2021-05-24 00:42:08 -07:00
```js
$(".text-primary").addClass("animated shake");
```

Debes usar la función jQuery `addClass()` para dar las clases `animated` y `shake` a todos tus elementos con la clase `well` .
2021-02-06 04:42:36 +00:00
```js
assert($('.well').hasClass('animated') & & $('.well').hasClass('shake'));
```
2021-09-07 07:47:37 -07:00
Debes usar solo jQuery para agregar estas clases al elemento.

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