Bootstrap4 進度條

2021-10-08 09:46 更新

進度條可以明確顯示用戶任務(wù)的完成進度，是日常使用頻率非常高的一項功能。在Bootstrap4中，進度條的創(chuàng)建也是相對比較簡單的。

進度條創(chuàng)建步驟：

1、添加一個帶有 .progress 類的 <div>。

2、接著，在上面的 <div> 內(nèi)，添加一個帶有 class .progress-bar 的空的 <div>。

3、添加一個帶有百分比表示的寬度的 style 屬性，例如 style="width:70%" 表示進度條在 70% 的位置。

實例

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>基本進度條</h2>
  <p>要創(chuàng)建一個默認的進度條，可以在容器元素上添加 .progress 類，在子元素上添加 progress-bar 類，并設(shè)置進度條進度情況：:</p>
  <div class="progress">
    <div class="progress-bar" style="width:70%"></div>
  </div>
</div>
</body>
</html>

進度條高度

進度條高度默認為 16px，不過我們可以使用 CSS 的 height 屬性來對高度進行修改：

實例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>進度條高度</h2>
  <p>進度條高度默認為 16px。我們可以使用 CSS 的 height 屬性來修改他：</p> 
  <div class="progress" style="height:10px">
    <div class="progress-bar" style="width:40%"></div>
  </div>
  </br>
  <div class="progress" style="height:20px">
    <div class="progress-bar" style="width:50%"></div>
  </div>
  </br>
  <div class="progress"style="height:30px">
    <div class="progress-bar" style="width:60%"></div>
  </div>
</div>
</body>
</html>

進度條寬度應(yīng)設(shè)置在progress上才能生效，progress-bar默認繼承progress的寬度。

進度條標簽

可以在進度條內(nèi)添加文本，如進度的百分比，這樣可以讓用戶一眼就看出當前任務(wù)的進度：

實例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>進度條文本標簽</h2>
  <div class="progress">
    <div class="progress-bar" style="width:70%">70%</div>
  </div>
</div>
</body>
</html>

進度條顏色

進度條默認是藍色，不過我們可以通過添加顏色類來對進度條的顏色進行修改。

實例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>多種顏色的進度條</h2>
  <p>Bootstrap4 提供了以下幾種進度條顏色:</p> 
  <div class="progress">
    <div class="progress-bar" style="width:30%"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar bg-success" style="width:40%"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar bg-info" style="width:50%"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar bg-warning" style="width:60%"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar bg-danger" style="width:70%"></div>
  </div>
</div>
</body>
</html>

條紋的進度條

可以使用 .progress-bar-striped 類來改變進度條的樣式，將其設(shè)置為條紋進度條。

實例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>條紋的進度條</h2>
  <p>可以使用 .progress-bar-striped 類來設(shè)置條紋進度條：</p> 
  <div class="progress">
    <div class="progress-bar progress-bar-striped" style="width:30%"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar bg-success progress-bar-striped" style="width:40%"></div>
  </div>
  <br>
  <div class="progress">
    <div class="progress-bar bg-info progress-bar-striped" style="width:50%"></div>
  </div>
</div>
</body>
</html>

進度條動畫

使用 .progress-bar-animated 類可以為進度條添加動畫：

實例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>動畫進度條</h2>
  <p>使用 .progress-bar-animated 類可以為進度條添加動畫：</p> 
  <div class="progress">
    <div class="progress-bar progress-bar-striped progress-bar-animated" style="width:40%"></div>
  </div>
</div>
</body>
</html>

混合色彩進度條

單個進度條可以設(shè)置成多種顏色：

實例：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 實例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
