For those purposes, there’s no better tech‐ nology to attempt to polyfill than HTML5 Forms. What we know of today as “HTML5 Forms” was actually the first technology to be proposed under the umbrella of what eventually became HTML5. 0 specification. 0, these vendors formed the Web Hypertext Application Technology Working Group (WHATWG), a sibling standards body to the W3C that still exists today.

In our case, however, I’ve chosen to use a UI library because it allows me to focus on the process of building polyfills, which is, after all, what this book is about. info | 25 all types of polyfills, without getting bogged down in the very complex specifics of building form UI by hand. The HTML5 Forms polyfill we will be building over the next three chapters can be found in its current form online on GitHub. The project is actively maintained, and you’re welcome to view the source after reading this book if you want to dig deeper into any specifics that I was unable to cover here.

GitHub automatically treats this file as the main entry point when anyone visits your project. It should describe the purpose and goals of the polyfill—as I discussed in Chapter 1—features of the project, a road map for the project, installation and usage instructions, and anything else you think might be useful to consumers of or collaborators on your polyfill.
