我发现了一些圆形进度条，但我不知道它们是如何填充的。这是一些代码笔的链接:https://codepen.io/anon/pen/aeEEmx
据我所知，当您使用渐变并添加位置(在本例中为度)时，它应该从您指定值的位置开始。例如，CSS中的progress-20类有一个18度的线性渐变，然后是另一个90度的线性渐变，但我无法理解这些值如何一起工作18度和90度或-18度和90度在那个30%的线性渐变中.
代码如下:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
html,
body {
background-color: #fff;
font-family: "Lato", "Arial", "san-serif";
color: #555;
font-size: 20px;
font-weight: 300px;
text-rendering: optimizeLegibility;
}
.radialProgressBar {
border-radius: 50%;
-webkit-transform: translate(50%, 50%);
transform: translate(50%, 50%);
width: 100px;
height: 100px;
display: -webkit-box;
display: -ms-flexbox;
display: flex;
background: #ddd;
margin: 20px;
}
.radialProgressBar .overlay {
border-radius: 50%;
width: 80px;
height: 80px;
margin: auto;
background: #fff;
text-align: center;
padding-top: 30%;
}
.progress-20 {
background-image: linear-gradient(18deg, #ddd 50%, transparent 50%), linear-gradient(90deg, #028cd5 50%, #ddd 50%);
}
.progress-30 {
background-image: linear-gradient(-18deg, #ddd 50%, transparent 50%), linear-gradient(90deg, #028cd5 50%, #ddd 50%);
}
.progress-40 {
background-image: linear-gradient(-54deg, #ddd 50%, transparent 50%), linear-gradient(90deg, #028cd5 50%, #ddd 50%);
}
.progress-70 {
background-image: linear-gradient(90deg, #028cd5 50%, transparent 50%), linear-gradient(18deg, #028cd5 50%, #ddd 50%);

这是使用几个重叠的渐变制成的。如果您对不同的渐变使用不同的颜色，您可以更容易地看到该方法。 90 度梯度将图表切成两半，而另一个梯度(本例中为 18 度)覆盖蓝色的其余部分，仅留下相关的蓝色部分可见。
