localeTitle: 使用具有Bootstrap Fluid Containers的响应式设计

## Description
<section id="description">在freeCodeCamp的HTML5和CSS部分，我们构建了一个Cat Photo App。现在让我们回到它。这一次，我们将使用流行的Bootstrap响应式CSS框架来设计它。 Bootstrap将通过调整HTML元素的大小来确定屏幕的宽度和响应 - 因此称为<code>Responsive Design</code> 。通过响应式设计，您无需设计网站的移动版本。在具有任何宽度的屏幕的设备上看起来都很好。您可以通过将以下代码添加到HTML顶部来将Bootstrap添加到任何应用程序： <code>&lt;link rel=&quot;stylesheet&quot; href=&quot;https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css&quot; integrity=&quot;sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u&quot; crossorigin=&quot;anonymous&quot;/&gt;</code>在这种情况下，我们已经在幕后为您添加了这个页面。请注意，使用<code>&gt;</code>或<code>/&gt;</code>关闭<code>link</code>标记是可以接受的。首先，我们应该将所有HTML（ <code>link</code>标签和<code>style</code>元素除外）嵌套在带有<code>container-fluid</code>类的<code>div</code>元素<code>container-fluid</code> 。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: 你的<code>div</code>元素应该有class <code>container-fluid</code> 。
    testString: 'assert($("div").hasClass("container-fluid"), "Your <code>div</code> element should have the class <code>container-fluid</code>.");'
  - text: 确保你的<code>div</code>元素有一个结束标记。
    testString: 'assert(code.match(/<\/div>/g) && code.match(/<div/g) && code.match(/<\/div>/g).length === code.match(/<div/g).length, "Make sure your <code>div</code> element has a closing tag.");'
  - text: 确保在<code>.container-fluid</code>的结束<code>style</code>标记之后嵌套了所有HTML元素。
    testString: 'assert($(".container-fluid").children().length >= 8, "Make sure you have nested all HTML elements after the closing <code>style</code> tag in <code>.container-fluid</code>.");'
