Bootstrap progress bar


This chapter will explain the Bootstrap progress bar. In this tutorial, you'll see how to use Bootstrap to create a progress bar for loading, redirect, or action states.

Bootstrap progress bars use CSS3 transitions and animations to achieve this effect. Internet Explorer 9 and earlier and older versions of Firefox do not support this feature, and Opera 12 does not support animations.

Default progress bar

The steps to create a basic progress bar are as follows:

  • Add a progress bar with class . <div> of progress.

  • Next, within the above <div>, add an empty <div> with class .progress-bar.

  • Add a style attribute with a width expressed in percentage, for example style="60%"; means the progress bar is at 60%.

Let’s look at the following example:

Instance

<!DOCTYPE html>
<html>
<head>
   <title>Bootstrap 实例 - 进度条</title>
   <link href="http://libs.baidu.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet">
<script src="http://libs.baidu.com/jquery/2.0.0/jquery.min.js"></script>
<script src="http://libs.baidu.com/bootstrap/3.0.3/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress">
   <div class="progress-bar" role="progressbar" aria-valuenow="60" 
      aria-valuemin="0" aria-valuemax="100" style="width: 40%;">
      <span class="sr-only">40% 完成</span>
   </div>
</div>

</body>
</html>

Alternating progress bar

The steps to create different styles of progress bars are as follows:

  • Add a <div> with class .progress.

  • Next, within the above <div>, add a class with class .progress-bar and class progress-bar-* of empty <div>. Among them, * can be success, info, warning, danger.

  • Add a style attribute with a width expressed in percentage, for example style="60%"; means the progress bar is at 60%.

Animated progress bar

The steps to create an animated progress bar are as follows:

  • Add a class with classes

    .progress and .progress-striped <div>. Also add class .active.
