# --description--
|
|
|
|
When HTML elements are placed one level below another they are called <dfn>children</dfn> of that element. For example, the button elements in this challenge with the text `#target1`, `#target2`, and `#target3` are all children of the `<div class="well" id="left-well">` element.
|
|
|
|
jQuery has a function called `children()` that allows you to access the children of whichever element you've selected.
|
|
|
|
Here's an example of how you would use the `children()` function to give the children of your `left-well` element the color `blue`:
|
|
|
|
```js
|
|
$("#left-well").children().css("color", "blue")
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
Give all the children of your `right-well` element the color orange.
|
|
|
|
# --hints--
|
|
|
|
All children of `#right-well` should have orange text.
|
|
|
|
```js
|
|
assert($('#right-well').children().css('color') === 'rgb(255, 165, 0)');
|
|
```
|
|
|
|
You should use the `children()` function to modify these elements.
|
|
|
|
```js
|
|
assert(code.match(/\.children\(\)\.css/g));
|
|
```
|
|
|
|
You should only use jQuery to add these classes to the element.
|
|
|
|
```js
|
|
assert(code.match(/<div class="well" id="right-well">/g));
|
|
```
