Styling Definition List using CSS

在以下示例中,我们使用 * CSS* 为定义列表设置样式。

<!DOCTYPE html>
<html>
<head>
   <style>
      body {
         font-family: Arial, sans-serif;
         margin: 20px;
      }
      dl {
         background-color: #f9f9f9;
         border: 1px solid #ddd;
         padding: 20px;
         border-radius: 5px;
         max-width: 400px;
         margin: 0 auto;
      }
      dt {
         font-weight: bold;
         color: #333;
         margin-top: 10px;
      }
      dd {
         margin: 0 0 10px 20px;
         color: #555;
      }

   </style>
</head>

<body>

      of video courses on various prominent

</dl>

</body>
</html>

Default CSS for Definition List

几乎所有浏览器都针对 <dl> 元素显示默认的 CSS 设置。在以下代码中,如果您删除样式,输出将不会改变,因为我们定义的样式是 <dl> 标签的默认样式。

<!DOCTYPE html>
<html>
<head>
   <!-- This is default style of Definition Lists -->
   <style>
      dl {
         display: block;
         margin-top: 1em;
         margin-bottom: 1em;
         margin-left: 0;
         margin-right: 0;
      }
   </style>
</head>

<body>
   <dl>
      <dt>Definition List</dt>
      <dd>
         A list of terms and their definitions.
      </dd>

      <dt>Android</dt>
      <dd>Android tutorial.</dd>

      <dt>Ruby</dt>
      <dd>Ruby tutorial.</dd>
