实际项目中li和里边的数值是动态生成的，需要控制它的宽度和颜色，效果如图：
如果能实现颜色按数值规律变化就好了，目前颜色是固定到数组中的。
实例代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style media="screen">
li{
padding-left: 20px;
list-style: none;
}
li>div{
height: 20px;
background-color: #038faa;
border-top-right-radius: 10px;
border-bottom-right-radius: 10px;
display: inline-block;
position: relative;
}
li>div>span{
display: inline-block;
position: absolute;
right: -22px;
}
</style>
</head>
<body>
<ul>
<li>
<div><span>56</span></div>
</li>
<li>
<div><span>18</span></div>
</li>
<li>
<div><span>16</span></div>
</li>
<li>
<div><span>13</span></div>
</li>
<li>
<div><span>11</span></div>
</li>
<li>
<div><span>9</span></div>
</li>
<li>
<div><span>9</span></div>
</li>
<li>
<div><span>8</span></div>
</li>
<li>
<div><span>7</span></div>
</li>
<li>
<div><span>7</span></div>
</li>
</ul>
