layui怎么加图标

layui加图标的方法：首先通过对一个内联元素设定“class="layui-icon"”，来定义一个图标；然后对元素加上图标对应的“font-class”即可。

推荐：《layui教程》

layui图标：

layui 的所有图标全部采用字体形式，取材于阿里巴巴矢量图标库（iconfont）点击打开链接矢量图标库。（https://www.iconfont.cn/）

使用方法：

通过对一个内联元素（一般推荐用 i标签）设定 class="layui-icon"，来定义一个图标，然后对元素加上图标对应的 font-class（注意：layui 2.3.0 之前只支持采用 unicode 字符)，即可显示出你想要的图标。内置图标的class查阅图标文档

从 layui 2.3.0 开始，支持 font-class 的形式定义图标：
<i class="layui-icon layui-icon-face-smile"></i>  
						
注意：在 layui 2.3.0 之前的版本，只能设置 unicode 来定义图标
<i class="layui-icon"></i>   
其中的  即是图标对应的 unicode 字符
						
你可以去定义它的颜色或者大小，如：  
<i class="layui-icon layui-icon-face-smile" style="font-size: 30px; color: #1E9FFF;"></i>

自定义阿里巴巴矢量图标库：

1. 按照其他人所说的步骤把阿里巴巴图标的图标代码下载到本地解压。

2. 在layui项目中创建一个文件夹，放入上面的几个文件，然后再引入iconfont.css文件即可使用：

<link rel="stylesheet" href="./plugins/layui/myicon/iconfont.css" type="text/css">

下载的iconfont.css文件如下

@font-face {font-family: "iconfont";  src: url('iconfont.eot?t=1529548540922'); /* IE9*/  src: url('iconfont.eot?t=1529548540922#iefix') format('embedded-opentype'), /* IE6-IE8 */  url('data:application/x-font-woff;charset=utf-8;base64,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') format('woff'),  url('iconfont.ttf?t=1529548540922') format('truetype'), /* chrome, firefox, opera, Safari, Android, iOS 4.2+*/  url('iconfont.svg?t=1529548540922#iconfont') format('svg'); /* iOS 4.1- */}

.iconfont { font-family:"iconfont" !important; font-size:16px; font-style:normal; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale;}

.icon-group:before { content: "\e6ff"; }

.icon-group_fill:before { content: "\e700"; }

iconfont.css文件如上（下载了两个图标），类名iconfont可以修改。将所有的iconfont字样替换成layui-icon。

3. html 引用：

<a class="layui-btn layui-btn-primary layui-btn-xs" lay-event="detail">
    <i class="layui-icon layui-icon-form"></i>查看<i class="iconfont icon-group"></i>
</a>
<a class="layui-btn layui-btn-xs" lay-event="edit">
    <i class="layui-icon layui-icon-edit"></i>编辑<i class="iconfont"></i>
</a>
<a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">
    <i class="layui-icon layui-icon-delete"></i>删除<i class="iconfont icon-empty"></i>
 </a>iconfont icon-group"></i>
</a>
<a class="layui-btn layui-btn-xs" lay-event="edit">
    <i class="layui-icon layui-icon-edit"></i>编辑<i class="iconfont"></i>
</a>
<a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">
    <i class="layui-icon layui-icon-delete"></i>删除<i class="iconfont icon-empty"></i>
 </a>
