把小图片转为Base64格式可有效减少http请求

现在主流的浏览器基本都支持Base64格式的文件,比如:

data:image/png;base64,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

是一个绿色的把小图片转为Base64格式可有效减少http请求小图标,图标虽小,但也得向服务器发送1个HTTP请求啊,一但像这样的小图片多了起来,网站流量也大了,服务器的压力会成倍增长。

// Base64 在CSS中的使用
.box{
  background-image: url("data:image/jpg;base64,/9j/4QMZR...");
}
// Base64 在HTML中的使用

Base64与CSS Sprite一样可用于解决服务器小图片请求问题,Base64转码后文件比实际的大30%,但是网站启用了GZIP,反而可以忽略增长的大小。Base64在小范围使用上完胜CSS Sprite,因为后者只适用于CSS,而Base64可以直接使用src方式引用。方便快捷。

对了,还可以参考awesome font的小图标技术。也是很牛的,后面我会用文章专门讲解使用awesome font把图标变成字体,可以无限放大缩小,改颜色神马的。。。。

最后,大家可以试试下面的代码(复制地址直接在浏览器地址栏里粘贴)。
