进度条使用 CSS3 过渡和动画来获得该效果。Internet Explorer 9 及之前的版本和旧版的 Firefox 不支持该特性，Opera 12 不支持动画。进度条的颜色样式有以下几种：.progress-bar-success、.progress-bar-info、.progress-bar-warning、.progress-bar-danger。

演示代码：

<body>
	<div class="container">
		<p>默认进度条</p>
		<div class="progress">
			<div class="progress-bar" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%;">
				<span class="sr-only">40% 完成</span>
			</div>
		</div>

		<p>不同色彩样式的进度条</p>
		<div class="progress">
			<div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="40" aria-valuemin="0" aria-valuemax="100" style="width: 40%;">
				<span class="sr-only">40% 完成</span>
			</div>
		</div>

		<p>条纹进度条</p>
		<div class="progress progress-striped">
			<div class="progress-bar progress-bar-danger" role="progressbar" aria-valuenow="80" aria-valuemin="0" aria-valuemax="100" style="width: 80%;">

	var num = 0;
	var timeID = setInterval(function() {
		$("#progress").css("width", num + "%")
		if(num >= 100) {
			clearInterval(timeID);
		} else {
			num += 1;
		}
	}, 100);
</script>
