我也是因为业务需要，需要给头像做一个进度条，查看效果图：
实现的代码也是网上搜索的，这里我讲解一下实现的原理：
使用svg画一个圆，然后分成5段，每段的颜色值可以渐变，当然也可以纯色，我是使用了纯色的。
下面来看一下CSS代码：
<style>
body {
background-color: #fff
}
@-webkit-keyframes load {
0% {
stroke-dashoffset: 0;
}
}
@keyframes load {
0% {
stroke-dashoffset: 0;
}
}
.progress {
position: relative;
display: inline-block;
padding: 0;
text-align: center;
}
.progress > li {
display: inline-block;
position: relative;
text-align: center;
color: #93A2AC;
font-family: Lato;
font-weight: 100;
margin: 2rem;
}
.progress > li:before {
content: attr(data-name);
position: absolute;
width: 100%;
bottom: -2rem;
font-weight: 400;
}
.progress > li:after {
content: attr(data-percent);
position: absolute;
width: 100%;
top: 3.7rem;
left: 0;
font-size: 2rem;
text-align: center;
}
.progress svg {
width: 10rem;
height: 10rem;
}
.progress svg:nth-child(2) {
position: absolute;
left: 0;
top: 0;
-webkit-transform: rotate(-90deg);
transform: rotate(-90deg);
}
.progress svg:nth-child(2) path {
fill: none;
stroke-width: 25;
stroke-dasharray: 629;
stroke: #fff;
opacity: .9;
-webkit-animation: load 10s;
animation: load 10s;
}
</style>
可以之间是10秒，如果喜欢短一点的，可以改一下样式“progress svg:nth-child(2) path”中的10s;
现在来看看html代码：
<ul class="progress">
<!-- Item -->
<li data-name="HTML5 Skill" data-percent="87%">
<svg viewBox="-10 -10 220 220">
<g fill="none" stroke-width="2" transform="translate(100,100)">
<path d="M 0,-100 A 100,100 0 0,1 86.6,-50" stroke="url(#cl1)"></path>
<path d="M 86.6,-50 A 100,100 0 0,1 86.6,50" stroke="url(#cl2)"></path>
<path d="M 86.6,50 A 100,100 0 0,1 0,100" stroke="url(#cl3)"></path>
<path d="M 0,100 A 100,100 0 0,1 -86.6,50" stroke="url(#cl4)"></path>
<path d="M -86.6,50 A 100,100 0 0,1 -86.6,-50" stroke="url(#cl5)"></path>
<path d="M -86.6,-50 A 100,100 0 0,1 0,-100" stroke="url(#cl6)"></path>
</g>
</svg>
<svg viewBox="-10 -10 220 220">
<path d="M200,100 C200,44.771525 155.228475,0 100,0 C44.771525,0 0,44.771525 0,100 C0,155.228475 44.771525,200 100,200 C155.228475,200 200,155.228475 200,100 Z"
stroke-dashoffset="547"></path>
</svg>
</li>
<!-- Item -->
<li data-name="jQuery Skill" data-percent="65%">
<svg viewBox="-10 -10 220 220">
<g fill="none" stroke-width="12" transform="translate(100,100)">
<path d="M 0,-100 A 100,100 0 0,1 86.6,-50" stroke="url(#cl1)"></path>
<path d="M 86.6,-50 A 100,100 0 0,1 86.6,50" stroke="url(#cl2)"></path>
<path d="M 86.6,50 A 100,100 0 0,1 0,100" stroke="url(#cl3)"></path>
<path d="M 0,100 A 100,100 0 0,1 -86.6,50" stroke="url(#cl4)"></path>
<path d="M -86.6,50 A 100,100 0 0,1 -86.6,-50" stroke="url(#cl5)"></path>
<path d="M -86.6,-50 A 100,100 0 0,1 0,-100" stroke="url(#cl6)"></path>
</g>
</svg>
<svg viewBox="-10 -10 220 220">
<path d="M200,100 C200,44.771525 155.228475,0 100,0 C44.771525,0 0,44.771525 0,100 C0,155.228475 44.771525,200 100,200 C155.228475,200 200,155.228475 200,100 Z"
stroke-dashoffset="200"></path>
</svg>
</li>
</ul>
其中data-name属性是标题名称，data-percent是中间的进度描述，我自己项目整理的时候把这段的CSS代码过滤了，因为我不需要显示这些，进度的控制是在svg中path元素的stroke-dashoffset属性中：
100%=629，也就是1%=6.29，自己根据进度乘一下。另外需要说一下的就是g元素中的stroke-width属性是控制宽度的。
颜色是在另外一个avg中控制的，可以看到path路径有一个stroke=”url(#cl6)”属性，这个就是控制段的颜色，下面附上代码：
<svg width="0" height="0">
<defs>
<lineargradient id="cl1" gradientUnits="objectBoundingBox" x1="0" y1="0" x2="1" y2="1">
<stop stop-color="#08DA24"></stop>

拷贝一下，就可以运行了。
