iconfont的使用——自定义与替换
一、原理：
字体图标是在 Web 项目中使用的图标字体，利用CSS3 @font-face 规则引入雪碧图文件，通过方位显示某个图标，常用图标可直接使用glyphicons/font-awesome;
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"> <i class="fa fa-home"></i>
<link rel="stylesheet" href="https://cdn.staticfile.org/twitter-bootstrap/3.3.7/css/bootstrap.min.css"> <span class="glyphicon glyphicon-search"></span>
自定义字体图标设置：以glyphicons源码设置为例
@font-face { font-family: ‘Glyphicons Halflings‘; src: url(‘../fonts/glyphicons-halflings-regular.eot‘); src: url(‘../fonts/glyphicons-halflings-regular.eot?#iefix‘) format(‘embedded-opentype‘), url(‘../fonts/glyphicons-halflings-regular.woff‘) format(‘woff‘), url(‘../fonts/glyphicons-halflings-regular.ttf‘) format(‘truetype‘), url(‘../fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular‘) format(‘svg‘); } .glyphicon { position: relative; top: 1px; display: inline-block; font-family: ‘Glyphicons Halflings‘; -webkit-font-smoothing: antialiased; font-style: normal; font-weight: normal; line-height: 1; -moz-osx-font-smoothing: grayscale; }
*注释：.glyphicon class声明一个从顶部偏移 1px 的相对位置，呈现为 inline-block，声明字体，规定 font-style 和 font-weight 为 normal，设置行高为 1。
除此之外，使用 -webkit-font-smoothing: antialiased 和 -moz-osx-font-smoothing: grayscale; 获得跨浏览器的一致性。
.glyphicon:empty {// 为空时保留宽度大小
width: 1em;
}
.glyphicon-user:before {// 用户头像字体图标方位
content: "\e008";
}
定制字体图标
默认图标显示
<button type="button" class="btn btn-primary btn-lg">
<span class="glyphicon glyphicon-user"></span> User
</button>
定制字体尺寸
通过增加或减少图标的字体尺寸，您可以让图标看起来更大或更小。
<button type="button" class="btn btn-primary btn-lg" style="font-size: 60px">
<span class="glyphicon glyphicon-user"></span> User
</button>
定制字体颜色
<button type="button" class="btn btn-primary btn-lg" style="color: rgb(212, 106, 64);">
<span class="glyphicon glyphicon-user"></span> User
</button>
应用文本阴影
<button type="button" class="btn btn-primary btn-lg" style="text-shadow: black 5px 3px 3px;">
<span class="glyphicon glyphicon-user"></span> User
</button>
在线定制字体图标
二、开发环境中使用：
这里介绍 Font Awesome ，它的图标库一共有675个图标，图标查询网址https://9iphp.com/fa-icons，后面自定义图标介绍iconfont 。
npm install font-awesome -S // 引入 import ‘font-awesome/css/font-awesome.css‘ // 1.全局使用：main.js <i class="iconfont icon-xxx"></i> // 2.直接使用：html
自定义字体图标iconfont：三种引用方式，各种字体图标文件与矢量图的引用自选使用
1.解压文件：登录官网——挑选图标到购物车——下载代码
2.引用本地文件：在自己项目中引入，可直接复制css文件中的代码，最长的是直接引用base64格式的雪碧图

url(‘iconfont.svg?t=1577411459799#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-file_jar:before {
content: "\e76d";
}
3.使用示例：
<i class="iconfont icon-file_jar">jar图标</i>
4.叠加或替换新的图标：如果有之前的图标建议重新打包

.my-iconfont {

}

.my-icon2-JAR:before {
content: "\e76d";
}
<i class="my-iconfont my-icon-xxx"></i> <i class="my-iconfont2 my-icon2-xxx"></i>
三、使用sass或less
这里举例sass的用法，关于sass的应用可以参考之前写的文章,除了语法问题，其他写法不变
[class^="my-icon-"],[class*=" my-icon2-"] { font-family: "iconfont" !important; font-size: 16px; font-style: normal; -webkit-font-smoothing: antialiased; -moz-osx-font-smoothing: grayscale; }
-end-
