• Handle inline styles
• Support for CSS preprocessor in the <style lang=""/>（Sass、Less、Stylus）
• Using PostCSS to transform CSS
• Supports merge postcss.config.js

Installation

Usage

const gulp = require('gulp')
const htmlCss = require('gulp-html-css')

gulp.task('process-html', () => {
  return gulp
    .src('src/**/*.html')
    .pipe(
      htmlCss(
        [
          /* PostCSS plugins */
        ],
        {
          /* options */
        }
      )
    )
    .pipe(gulp.dest('dist'))
})

Example

const gulp = require('gulp')
const htmlCss = require('gulp-html-css')
const autoprefixer = require('autoprefixer')
const cssnano = require('cssnano')
const sass = require('sass')

gulp.task('process-html', () => {
  return gulp
    .src('src/**/*.html')
    .pipe(
      htmlCss([autoprefixer(), cssnano()], {
        compiler: sass,
        compilerOptions: {
          // Sass options
        },
        postcss: {
          // PostCSS options
        },
      })
    )
    .pipe(gulp.dest('dist'))
})

This example processes HTML files, compiling Sass within <style lang="sass"> tags, then applies Autoprefixer and minifies the CSS using cssnano.
