title: Target the Children of an Element Using jQuery
|
|
challengeType: 6
|

|
|
|
|
## Description
|
|
<section id='description'>
|
|
When HTML elements are placed one level below another they are called <code>children</code> of that element. For example, the button elements in this challenge with the text "#target1", "#target2", and "#target3" are all <code>children</code> of the <code><div class="well" id="left-well"></code> element.
|
|
jQuery has a function called <code>children()</code> that allows you to access the children of whichever element you've selected.
|
|
Here's an example of how you would use the <code>children()</code> function to give the children of your <code>left-well</code> element the color <code>blue</code>:
|
|
<code>$("#left-well").children().css("color", "blue")</code>
|
|
</section>
|
|
|
|
## Instructions
|
|
<section id='instructions'>
|
|
Give all the children of your <code>right-well</code> element the color orange.
|
|

```yml
|
|
tests:
|
|
- text: All children of <code>#right-well</code> should have orange text.
|
|
testString: assert($("#right-well").children().css("color") === 'rgb(255, 165, 0)', 'All children of <code>#right-well</code> should have orange text.');
|
|
- text: You should use the <code>children()</code> function to modify these elements.
|
|
testString: assert(code.match(/\.children\(\)\.css/g), 'You should use the <code>children()</code> function to modify these elements.');
|
|
- text: Only use jQuery to add these classes to the element.
|
|
testString: assert(code.match(/<div class="well" id="right-well">/g), 'Only use jQuery to add these classes to the element.');
