gulp-pxrem

This is a gulp plugin for px2rem

CLI tool provided in px2rem

Usage

The raw stylesheet only contains @2x style, and if you

• don't intend to transform the original value, eg: 1px border, add /*no*/ after the declaration
• intend to use px by force，eg: font-size, add /*px*/ after the declaration

Attention: Dealing with SASS or LESS, only /*...*/ comment can be used, in order to have the comments persisted

Gulpfile.js：

var gulp = require('gulp');
var px2rem = require('gulp-pxrem');

gulp.task('px2rem', function() {
  gulp.src('./*.css')
    .pipe(px2rem())
    .pipe(gulp.dest('./dest'))
});

Options

px2rem({
  baseDpr: 2,             // base device pixel ratio (default: 2)
  threeVersion: false,    // whether to generate @1x, @2x and @3x version (default: false)
  remVersion: true,       // whether to generate rem version (default: true)
  remUnit: 75,            // rem unit value (default: 75)
