HomeWeb Front-endCSS TutorialUse icon fonts to assist CSS in image processing

这篇文章主要介绍了使用icon fonts来辅助CSS处理图片,在移动端网页的设计中使用较多,需要的朋友可以参考下

由于移动端设备拥有不同分辨率,PPI 等引起的问题, 常常需要针对不同屏幕分辨率来调整优化,如使用 @2x 图片, max-width 限制等。
采用 css @font-face 用来显示 icon 也不失为一种好办法。
因为 icon fonts (字体)是矢量图形,所以不受分辨率的影响,同时可以做到完美缩放;当然,也可使用在 WEB 端。
优点

    文件小
    加载性能好
    支持 css 样式
    IE6/7 下也支持

缺点

    样式限制,使用扁平化风格
    移动端还存在不兼容问题 

    少量移动设备和 icon fonts 字符编码冲突
    FF和 IE9 下跨域问题
    性能问题

使用方法

    制作字体文件
        可以利用字体工具手动制作
        也可以利用在线工具自动生成
    在 css 中引用,如下

引入字体文件

@font-face {font-family: 'iconfont';   
    src: url('iconfont.eot'); /* IE9*/
    src: url('iconfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
    url('iconfont.woff') format('woff'), /* chrome、firefox */
    url('iconfont.ttf') format('truetype'), /* chrome、firefox、opera、Safari, Android, iOS 4.2+*/
    url('iconfont.svg#uxiconfont') format('svg'); /* iOS 4.1- */
}

再定义一个 icon-* 通配我们所有图标的共有 CSS 样式,

[class^="icon-"], [class*=" icon-"] {   
  display: inline-block;   
  speak: none
  font-family: "iconfont";   
  font-size: 16px;   
  line-height: 1;   
  font-style: normal;   
  /** 字体图标出现锯齿的问题: */
  -webkit-font-smoothing: antialiased;   
  -moz-osx-font-smoothing: grayscale;   
}

最后是利用 :before 来注入每个 icon 对应的字体编码

.icon-bell:before {   
  content: "\003432";   
}   
.icon-search:before {   
  content: "\003433";   
}
