纯CSS实现饼图、环形图（百分比）

本篇文章详细介绍了如何使用纯CSS实现饼状图以及环形图，并且附带有源代码

一、饼状图

CSS

.pie {
    width: 100px;
    height: 100px;
    border-radius: 50%;
    background: yellowgreen;
    background-image: linear-gradient(to right, transparent 50%, #655 0);
}
 
.pie::before {
    content: '';
    display: block;
    margin-left: 50%;
    height: 100%;
    border-radius: 0 100% 100% 0/50%;
    background-color: inherit;
    transform-origin: left;
    transform: rotate(.2turn);
}

HTML

<div class="pie"></div>

二、环形图

CSS

.loading {
    margin: 100px auto;
    width: 8em;
    height: 8em;
    position: relative;
}
 
.loading .progress {
    position: absolute;
    width: 6em;
    height: 6em;
    background-color: white;
    border-radius: 50%;
    left: 1em;
    top: 1em;
    line-height: 6em;
    text-align: center;
}
 
.left,
.right {
    width: 4em;
    height: 8em;
    overflow: hidden;
    position: relative;
    float: left;
    background-color: #999999
}
 
.left {
    border-radius: 8em 0 0 8em;
}
 
.right {
    border-radius: 0 8em 8em 0;
}
 
.left:after,
.right:after {
    content: "";
    position: absolute;
    display: block;
    width: 4em;
    height: 8em;
    background-color: white;
    border-radius: 8em 0 0 8em;
    background-color: red;
}
 
.right:after {
    content: "";
    position: absolute;
    display: block;
    border-radius: 0 8em 8em 0;
}
.left:after {
    transform-origin: right center;
}
 
.right:after {
    transform-origin: left center;
    transform: rotateZ(45deg);
}

HTML

<div class="loading">
    <div class="left"></div>
    <div class="right"></div>
    <div class="progress">85%</div>
</div>
