Bootstrap4 进度条

由 平台活动 创建, 最后一次修改 2018-05-29

进度条可以明确显示用户任务的完成进度,是日常使用频率非常高的一项功能。在Bootstrap4中,进度条的创建也是相对比较简单的。


进度条创建步骤:

1、添加一个带有 .progress 类的 <div>。

2、接着,在上面的 <div> 内,添加一个带有 class .progress-bar 的空的 <div>。

3、添加一个带有百分比表示的宽度的 style 属性,例如 style="width:70%" 表示进度条在 70% 的位置。

<div class="container">
  <h2>基本进度条</h2>
  <p>要创建一个默认的进度条,可以在容器元素上添加 .progress 类,在子元素上添加 progress-bar 类,并设置进度条进度情况::</p>
  <div class="progress">
    <div class="progress-bar" style="width:70%"></div>
  </div>
</div>
</body>
</html>


进度条高度

进度条高度默认为 16px,不过我们可以使用 CSS 的 height 属性来对高度进行修改:

实例:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/4.1.0/css/bootstrap.min.css">
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js"></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
  <h2>进度条高度</h2>
  <p>进度条高度默认为 16px。我们可以使用 CSS 的 height 属性来修改他:</p> 
  <div class="progress">
    <div class="progress-bar" style="width:40%;height:10px"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar" style="width:50%;height:20px"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar" style="width:60%;height:30px"></div>
  </div>
</div>
</body>
</html>


进度条标签

可以在进度条内添加文本,如进度的百分比,这样可以让用户一眼就看出当前任务的进度:

实例:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/4.1.0/css/bootstrap.min.css">
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js"></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
  <h2>进度条文本标签</h2>
  <div class="progress">
    <div class="progress-bar" style="width:70%">70%</div>
  </div>
</div>
</body>
</html>


进度条颜色

进度条默认是蓝色,不过我们可以通过添加颜色类来对进度条的颜色进行修改。

实例:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/4.1.0/css/bootstrap.min.css">
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js"></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
  <h2>多种颜色的进度条</h2>
  <p>Bootstrap4 提供了以下几种进度条颜色:</p>

</div>
</body>

条纹的进度条

可以使用 .progress-bar-striped 类来改变进度条的样式,将其设置为条纹进度条。
