排版

Bootstrap4 采用了一些简单易用的自定义排版元素，让用户可以对标题、正文、表格等等能够自由定义。下面就一起来看看具体内容吧。

Bootstrap4 默认设置

Bootstrap4 默认的 font-size 为 16px, line-height 为 1.5。

默认的 font-family 为 "Helvetica Neue", Helvetica, Arial, sans-serif。

此外，所有的 <p> 元素 margin-top: 0 、 margin-bottom: 1rem (16px)。

标题

Bootstrap4 中定义了所有的 HTML 标题（h1 到 h6）的样式。请看下面的实例：

<div class="container">
  <h1>h1 Bootstrap 标题 (2.5rem = 40px)</h1>
  <h2>h2 Bootstrap 标题 (2rem = 32px)</h2>
  <h3>h3 Bootstrap 标题 (1.75rem = 28px)</h3>
  <h4>h4 Bootstrap 标题 (1.5rem = 24px)</h4>
  <h5>h5 Bootstrap 标题 (1.25rem = 20px)</h5>
  <h6>h6 Bootstrap 标题 (1rem = 16px)</h6>
</div>

Display 标题类

Bootstrap 还提供了四个 Display 类来控制标题的样式: .display-1, .display-2, .display-3, .display-4。

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
