    虽然我们现在大都使用字体图标或者svg图片，似乎使用 CSS 来做图标意义不是很大，但怎么实现这些图标用到的一些技巧及思路是很值得我们的学习。

    一、实心圆

    .circle {
    width: 120px;
    height: 120px;
    background: #8BC34A;
    border-radius: 100%;
}

    二、圆环（空心圆）

    .ring {
    width: 100px;
    height: 100px;
    border: 10px solid #8BC34A;
    border-radius: 100%;
}

    三、椭圆

    clipboard.png

    .ellipsis {
    width: 200px;
    height: 120px;
    background: #8BC34A;
    border-radius: 100px/60px;
}

    四、半圆

    .top-semicircle {
    width: 120px;
    height: 60px;
    background: #8BC34A;
    border-radius: 60px 60px 0px 0px;
}

.right-semicircle {
    width: 60px;
    height: 120px;
    background: #8BC34A;
    border-radius: 0 60px 60px 0;
}

.bottom-semicircle {
    width: 120px;
    height: 60px;
    background: #8BC34A;
    border-radius: 0 0 60px 60px;
}
