Examples: Bootstrap 4 Devise Forms (using haml)

Devise views converted to HAML and integrated with Bootstrap 4 styling.

In other words, rails generate devise:views translated into Haml and Bootstrap 4 (docs). I worked through this the other day and thought I’d share.

In addition to applying the Bootstrap 4 classes and form structure, I also pulled out most of the English language text into a locale file and added optional classes to various elements for further customization.

Suggestions, questions and comments are welcome!
