## Description
<section id="description">当HTML元素放在另一个下面时，它们被称为该元素的<code>children</code>元素。例如，在与文本“＃Target1时”，“＃TARGET2”，和“＃target3”这一挑战的按钮元件都是<code>children</code>的的<code>&lt;div class=&quot;well&quot; id=&quot;left-well&quot;&gt;</code>元素。 jQuery有一个名为<code>children()</code>的函数，允许您访问您选择的元素的子元素。下面是一个示例，说明如何使用<code>children()</code>函数为<code>left-well</code>元素的子项设置<code>blue</code> ： <code>$(&quot;#left-well&quot;).children().css(&quot;color&quot;, &quot;blue&quot;)</code> </section>

## Instructions
<section id="instructions">给你的<code>right-well</code>元素的所有孩子颜色为橙色。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: '<code>#right-well</code>所有孩子都应该有橙色文字。'
    testString: 'assert($("#right-well").children().css("color") === "rgb(255, 165, 0)", "All children of <code>#right-well</code> should have orange text.");'
  - text: 您应该使用<code>children()</code>函数来修改这些元素。
    testString: 'assert(code.match(/\.children\(\)\.css/g), "You should use the <code>children&#40&#41</code> function to modify these elements.");'
  - text: 只使用jQuery将这些类添加到元素中。
    testString: 'assert(code.match(/<div class="well" id="right-well">/g), "Only use jQuery to add these classes to the element.");'

```
