HTML5 Boilerplate or h5bp is a popular front-end template. This tool is a set of front-end rules that perfectly meets the needs of a developer who wants to start his project quickly and cleanly without having to download libraries here and there and write dozens of lines of HTML.

How does HTML5 Boilerplate work?

You can download HTML5 Boilerplate from https://html5boilerplate.com/.   

The .zip file is made up of folders containing HTML, js, basic CSS and a few images so you can start a web project on a solid existing base instead of starting from scratch.

There's also extensive documentation available on github.

In short, the aim of this template is to bring together a maximum number of best practices for the web, namely: quality, accessibility, performance and above all productivity.
