If you are familiar with the excellent HTML5 Boilerplate then Initializr will blow your mind. While HTML5 Boilerplate is an amazing starter pack for your projects sometimes it just feels too much. With Initializr you can select which components (html, javascript, htaccess or any other html5 boilerplate component) you want to use in some really easy steps. You can then have your codes uploaded to your web host and see their actual appearance online.
