In this tutorial, you will 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. (Recommended learning: Bootstrap video tutorial)

Animated progress bar

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

Add a

with classes .progress and .progress-striped.

Add class .active at the same time.

Next, within the above

, add an empty

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%.

This will give the stripes a sense of movement from right to left.

Let us take a look at the following example:

<!DOCTYPE html>
<html>
<head>
	<meta charset="utf-8"> 
	<title>Bootstrap 实例 - 动画的进度条</title>
	<link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css">
	<script src="https://cdn.staticfile.org/jquery/2.1.1/jquery.min.js"></script>
	<script src="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<div class="progress progress-striped active">
	<div class="progress-bar progress-bar-success" 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>
