如何使用CSS和Javascript来缩小HTML？

我有一个.html文件与CSS和 Javascript里面的文件(没有外部文件).有没有一些在线工具,可以将文档和Javascript缩小到一小部分？我看到许多不可读的脚本,其中所有变量和函数名称都被替换为一个字母的名字等.请咨询.

解决方法

将所有.css文件移动到一个文件中并将其缩小的配置示例：

{
  test: /\.css$/,use: [
    {
      loader: 'css-loader',options: {
        minimize: true
      }
    }
  ]
}

Task runners are small applications that are used to automate many of
the time consuming,boring (but very important) tasks that you have to
do while developing a project. These include tasks such as running
tests,concatenating files,minification,and CSS preprocessing. By
simply creating a task file,you can instruct the task runner to
automatically take care of just about any development task you can
think of as you make changes to your files. It’s a very simple idea
that will save you a lot of time and allow you to stay focused on
development.

必读：Getting started with Gulp.js

使用JavaScript连接和分类(和JSHint)的任务示例：

gulp.task('scripts',function() {
  return gulp.src('src/scripts/**/*.js')
    .pipe(jshint('.jshintrc'))
    .pipe(jshint.reporter('default'))
    .pipe(concat('main.js'))
    .pipe(gulp.dest('dist/assets/js'))
    .pipe(rename({suffix: '.min'}))
    .pipe(uglify())
    .pipe(gulp.dest('dist/assets/js'))
    .pipe(notify({ message: 'Scripts task complete' }));
});

原来的答案(2012年7月19日)：我建议HTML5 Boilerplate Build Script可以减少你的JS和CSS.
