在本教程中，您将看到如何使用 Bootstrap 创建加载、重定向或动作状态的进度条。

请注意，如果要显示第三种进度条，请添加 '.active' class 来让它具有运动感。Bootstrap 使用 css3 过渡效果创建这个动画。您也可以通过 JavaScript 动态地调整进度条的宽度。这样，就可以掌握进度行为。
在创建进度条时，您可以使用其他的颜色。

我们已经在不同的浏览器中测试了上面的两个实例。我们发现，在 Firefox 12 和 Chrome 19.0.1084.52 中能正常显示，但是在 Opera 11.62 中不能显示动画效果，即便您可以看到条纹和梯度。在 Internet Explorer 8 中，所有的显示效果都不佳，没有动画，也没有条纹和梯度。
