CSS代码如下：

#yin-yang {
        width: 96px;
        height: 48px;
        background: #eee;
        border-color: red;
        border-style: solid;
        border-width: 2px 2px 50px 2px;
        border-radius: 100%;
        position: relative;
    }
    
    #yin-yang:before {
        content: "";
        position: absolute;
        top: 50%;
        left: 0;
        background: #eee;
        border: 18px solid red;
        border-radius: 100%;
        width: 12px;
        height: 12px;
    }
    
    #yin-yang:after {
        content: "";
        position: absolute;
        top: 50%;
        left: 50%;
        background: red;
        border: 18px solid #eee;
        border-radius:100%;
        width: 12px;
        height: 12px;
    }
