UI Elements

A collection of UI element samples written with vanilla web platform features.

Please note: these are prototypes, and not production-ready. The aim is to demonstrate a solid approach for building performant UI elements.

Getting started

  1. Clone the repo.
  2. Open an element's subfolder.
  3. Run index.html

ES2015 and ES5 Transpilation

Please note: these samples are written in ES2015 and, as such, require direct browser support. You can transpile the examples with BabelJS:

babel --presets=es2015 swipeable-cards/cards.js --out-file swipeable-cards/cards-es5.js
babel --presets=es2015 side-nav/side-nav.js --out-file side-nav/side-nav-es5.js

But to keep things as simple as possible for everyone, that's out of scope for this set of samples.
