Bootstrap - 媒体对象( Media Object)

本章讨论Media对象。 这些是抽象对象样式，用于构建各种类型的组件（如博客评论，推文等），这些组件在文本内容旁边具有左对齐或右对齐图像。 媒体对象的目标是使用于开发这些信息块的代码大大缩短。

媒体对象的目标（轻量级标记，易扩展性）是通过将类应用于某些简单标记来实现的。 媒体对象有两种形式 -

• .media - 此类允许将媒体对象（图像，视频和音频）浮动到内容块的左侧或右侧。

• .media-list - 如果您准备的列表中的项目将成为无序列表的一部分，请使用类。 对评论主题或文章列表有用。

让我们看一下默认媒体对象的下面一个例子 -

<div class = "media">
   <a class = "pull-left" href = "#">
      <img class = "media-object" src = "/bootstrap/images/64.jpg" alt = "Media Object">
   </a>
   <div class = "media-body">
      <h4 class = "media-heading">Media heading</h4>

让我们看一下媒体列表的一个例子 -

   <li class = "media">

         <img class = "media-object" src = "/bootstrap/images/64.jpg" alt = "Generic placeholder image">
      </a>
      <div class = "media-body">
         <h4 class = "media-heading">Media heading</h4>
