HTML代码

HTML的代码非常简单，只要为进度条提供一个容器就可以了。基本的HTML代码如下：

.load-bar-inner {
height: 99%;
width: 0%;
border-radius: inherit;
position: relative;
background: #c2d7ac;
background: linear-gradient(#e0f6c8, #98ad84);
box-shadow: inset 0 1px 0 rgba(255, 255, 255, 1), 0 1px 5px rgba(0, 0, 0, 0.3), 0 4px 5px rgba(0, 0, 0, 0.3);

}
