localeTitle: Ditch Custom CSS for Bootstrap

## Description
<section id="description">我们可以使用Bootstrap的内置样式代替我们之前创建的自定义样式来清理代码并使我们的Cat Photo App看起来更加传统。别担心 - 以后会有足够的时间来定制CSS。从<code>style</code>元素中删除<code>.smaller-image</code> <code>.red-text</code> ， <code>p</code>和<code>.smaller-image</code> CSS声明，以便<code>style</code>元素中剩下的唯一声明是<code>h2</code>和<code>thick-green-border</code> 。然后删除包含死链接的<code>p</code>元素。然后从<code>h2</code>元素中删除<code>red-text</code>类，并将其替换为<code>text-primary</code> Bootstrap类。最后，从第一个<code>img</code>元素中删除“small-image”类，并将其替换为<code>img-responsive</code>类。 </section>

## Tests
<section id='tests'>

```yml
tests:
  - text: 你的h2元素不应该有<code>red-text</code>类。
    testString: 'assert(!$("h2").hasClass("red-text"), "Your h2 element should no longer have the class <code>red-text</code>.");'
  - text: 您的h2元素现在应该具有<code>text-primary</code>类。
    testString: 'assert($("h2").hasClass("text-primary"), "Your h2 element should now have the class <code>text-primary</code>.");'
  - text: 您的段落元素不应再使用<code>Monospace</code> 。
    testString: 'assert(!$("p").css("font-family").match(/monospace/i), "Your paragraph elements should no longer use the font <code>Monospace</code>.");'
  - text: 从顶部图像中删除<code>smaller-image</code>类。
    testString: 'assert(!$("img").hasClass("smaller-image"), "Remove the <code>smaller-image</code> class from your top image.");'
  - text: 将<code>img-responsive</code>类添加到您的顶部图像。
    testString: 'assert($(".img-responsive").length > 1, "Add the <code>img-responsive</code> class to your top image.");'
