tool-gulpcsswrap's Introduction

tool-gulpcsswrap [批量给css文件增加命名空间]

说明:

使用的是npm包gulp-css-wrap

gulp使用指南

如我们给css文件的每个加上.custom-1b1e24类名

原css文件:

.header{height:100px;}

.content{color:#fff;}

=>输出

.custom-1b1e24 .header{height:100px;}

.custom-1b1e24 .content{color:#fff;}

运行:

//1.安装gulp命令行工具:
npm install --global gulp-cli

//2.安装gulp:
npm install gulp

//3.安装gulp-clean-css
npm install gulp-clean-css

//4.安装gulp-css-wrap
npm install gulp-css-wrap

// 一起安装
npm install gulp gulp-clean-css gulp-css-wrap -D

package.json 中已有,可直接安装

npm install

gulp css-wrap

P.S

如果要换存放目录或者修改前缀则只需修改根目录下的gulpfile.js 文件即可

var path = require('path')
var gulp = require('gulp')
var cleanCSS = require('gulp-clean-css')
var cssWrap = require('gulp-css-wrap')
gulp.task('css-wrap', function () {
    return gulp.src(path.resolve('./red.css'))
    /* 找需要添加命名空间的css文件,支持正则表达式 */
        .pipe(cssWrap({
            selector: '.custom-red' /* 添加的命名空间 */
        }))
        .pipe(cleanCSS())
        .pipe(gulp.dest('css/')) /* 存放的目录 */
})
