#css-urlbase64
a tool to conver the url in css background-image to base64.
严格来讲,这是一个nodejs模块,并不是gulp插件,它可以让你的css文件中background-image里面引用的图片资源转化为base64数据,以减少网络请求,提高页码性能和加载速度。
注意:请不要将大图片转换为base64,会严重降低页码性能!!!
##用法
在使用之前,请为需要转换的图片引用加上转换标记: 比如:
.myImg{
background-image: url("image/p1.png?base64");
}
或者
.myImg{
background: url("image/p1.png?base64") 0 0 no-repeat;
}
如果你需要在gulp里面使用,可以这样:
var urlbase64 = require('css-urlbase64');
gulp.task('tobase64', function(){
urlbase64('./css/style.css');
});
后续版本会添加如下功能: 1.增加图片大小判断功能,通过传入制定图片大小,如果小于该大小的图片,统一转换为base64 2.将base64数据封装到JSON文件里面,单独加装,减少css文件体积
