主要运用了CSS的几个属性transform-origin/rotate/skewY，还不懂的赶快去看看哈。
三个div实现

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>核辐射警告标志</title>
</head>
<style type="text/css">
html,body {
  width: 100%;
  height: 100%;
}
#warning {
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  width: 200px;
  height: 200px;
  border-radius: 100%;
  background-color: yellow;
  overflow: hidden;
}
.sector {
    position: absolute;
    top: 0;
    right: 0;
    width: 50%;
    height: 50%;
    transform-origin: 0% 100%;
}
.sector:nth-child(1) {
    transform: rotate(30deg) skewY(-30deg);
    background: black;
}
.sector:nth-child(2) {
    transform: rotate(-90deg) skewY(-30deg);
    background: black;
}
.sector:nth-child(3) {
    transform: rotate(-210deg) skewY(-30deg);
    background: black;
}
</style>
<body>
    <div id="warning">
        <div class="sector"></div>
        <div class="sector"></div>
        <div class="sector"></div>
    </div>
</body>
</html>

    width: 50%;
    height: 50%;
    transform-origin: 0% 100%;
}
.sector:nth-child(1) {
    transform: rotate(30deg) skewY(-30deg);
    background: black;
}
.sector:nth-child(2) {
    transform: rotate(-30deg) skewY(-30deg);
    background: yellow;
}
.sector:nth-child(3) {
    transform: rotate(-90deg) skewY(-30deg);
    background: black;
}
.sector:nth-child(4) {
    transform: rotate(-150deg) skewY(-30deg);
    background: yellow;
}
.sector:nth-child(5) {
    transform: rotate(-210deg) skewY(-30deg);
    background: black;
}
.sector:nth-child(6) {
    transform: rotate(-270deg) skewY(-30deg);
    background: yellow;
}
</style>
<body>
    <div id="warning">
        <div class="sector"></div>
