6、iconfont用法

<!DOCTYPE html>
<html lang="en">

    <meta charset="UTF-8">
    <title></title>

        @font-face {font-family: 'iconfont';
            src: url('./font/iconfont.eot');
            src: url('./font/iconfont.eot?#iefix') format('embedded-opentype'),
            url('./font/iconfont.woff') format('woff'),
            url('./font/iconfont.ttf') format('truetype'),
            url('./font/iconfont.svg#iconfont') format('svg');
        }

        .iconfont{
            font-family:"iconfont" !important;
            font-size:16px;font-style:normal;
            -webkit-font-smoothing: antialiased;
            -webkit-text-stroke-width: 0.2px;
            -moz-osx-font-smoothing: grayscale;
        }
        .aa{
            font-size: 20px;
        }
