# --description--
|
||
|
|
|
||
|
|
Recall that in addition to class attributes, you can give each of your elements an `id` attribute.
|
||
|
|
|
||
|
|
Each id must be unique to a specific element and used only once per page.
|
||
|
|
|
||
|
|
Let's give a unique id to each of our `div` elements of class `well`.
|
||
|
|
|
||
|
|
Remember that you can give an element an id like this:
|
||
|
|
|
||
|
|
```html
|
||
|
|
<div class="well" id="center-well">
|
||
|
|
```
|
||
|
|
|
||
|
|
Give the well on the left the id of `left-well`. Give the well on the right the id of `right-well`.
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
Your left `well` should have the id of `left-well`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(
|
||
|
|
$('.col-xs-6').children('#left-well') &&
|
||
|
|
$('.col-xs-6').children('#left-well').length > 0
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
Your right `well` should have the id of `right-well`.
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert(
|
||
|
|
$('.col-xs-6').children('#right-well') &&
|
||
|
|
$('.col-xs-6').children('#right-well').length > 0
|
||
|
|
);
|
||
|
|
```
