GoogleChrome/howto-components: Literate code examples for common UI patterns.

“HowTo: Components” is a subsection on Web Fundamentals Architecture section, containing a collection of web components that implement common web UI patterns using modern web technologies like Custom Elements v1 and ESnext with a special focus on accessibility, performance and progressive enhancement. Their purpose is to be an educational resource. Users are supposed to read and learn from their implementations. They are explicitly NOT a UI library meant to be used in production.
