Getting Started

Install this grunt plugin next to your project’s Gruntfile.js with:

npm install grunt-html --save-dev

Then add this line to your project’s Gruntfile.js:

grunt.loadNpmTasks('grunt-html');

Then specify what files to validate in your config:

grunt.initConfig({
  htmllint: {
    all: ["demos/**/*.html", "tests/**/*.html"]
  }
});

For fast validation, keep that in a single group, as the validator initialization takes a few seconds.
