終端
1、npm init （創(chuàng)建package.json
2俩滥、npm install autoprefixer postcss-color-rgba-fallback postcss-opacity postcss-pseudoelements postcss-vmin pixrem postcss-will-change--save-dev
3晒旅、gulpfile.js添加
var gulp = require('gulp');
var postcss = require('gulp-postcss');
var autoprefixer = require('autoprefixer');
var color_rgba_fallback = require('postcss-color-rgba-fallback');
var opacity = require('postcss-opacity');
var pseudoelements = require('postcss-pseudoelements');
var vmin = require('postcss-vmin');
var pixrem = require('pixrem');
var will_change = require('postcss-will-change');
gulp.task('css', function () {
? ? var processors = [
? ? ? ? will_change,
? ? ? ? autoprefixer,
? ? ? ? color_rgba_fallback,
? ? ? ? opacity,
? ? ? ? pseudoelements,
? ? ? ? vmin,
? ? ? ? pixrem
? ? ];
? ? return gulp.src('./src/*.css')
? ? ? ? .pipe(postcss(processors))
? ? ? ? .pipe(gulp.dest('./dest'));
});
