## 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>
