Source Maps

Use gulp-sourcemaps like this:

const gulp = require('gulp');
const sourcemaps = require('gulp-sourcemaps');
const autoprefixer = require('gulp-autoprefixer');
const concat = require('gulp-concat');

gulp.task('default', () =>
	gulp.src('src/**/*.css')
		.pipe(sourcemaps.init())
		.pipe(autoprefixer())
		.pipe(concat('all.css'))
		.pipe(sourcemaps.write('.'))
		.pipe(gulp.dest('dist'))
);

Tip

If you use other PostCSS based tools, like cssnano, you may want to run them together using gulp-postcss instead of gulp-autoprefixer. It will be faster, as the CSS is parsed only once for all PostCSS based tools, including Autoprefixer.
