## Description
|
||
<section id="description"> Bootstrap使用响应式12列网格系统，可以轻松地将元素放入行中并指定每个元素的相对宽度。 Bootstrap的大多数类都可以应用于<code>div</code>元素。 Bootstrap具有不同的列宽属性，具体取决于用户屏幕的宽度。例如，手机屏幕较窄，笔记本电脑屏幕较宽。以Bootstrap的<code>col-md-*</code>类为例。这里， <code>md</code>表示中等， <code>*</code>是指定元素应该有多少列的数字。在这种情况下，正在指定中型屏幕（例如笔记本电脑）上的元素的列宽。在我们正在构建的Cat照片应用程序中，我们将使用<code>col-xs-*</code> ，其中<code>xs</code>表示超小（如超小型手机屏幕）， <code>*</code>是指示列宽多少列的列数元素应该是。通过将所有三个嵌套在一个<code><div class="row"></code>元素中，然后将它们中的每一个<code><div class="col-xs-4"></code>元素中，将<code>Like</code> ， <code>Info</code>和<code>Delete</code>按钮并排放置。 <code>row</code>类应用于<code>div</code> ，按钮本身可以嵌套在其中。 </section>
