Front-End Bookmarks

This is a collection of essential (or just useful/inspirational) Front-End
Development & Accessibility bookmarks, frequently used in our daily work.

I try to keep this list generic (with a few exceptions), focusing on higher level
concepts instead, such as accessibility, architecture, performance, code quality,
workflow and best practices.

This is a living document (no shit!).
