Coding style

The code use ES6 (Javascript 2015) features and follow AirBnb javascript style guide (2-spaces indent, space before leading brace and opening parenthesis in control statements, etc.) with a few amendments (like "allows camelcase", "plusplus in for loop" and "mixed operators"; see the .eslintrc.json file for details).
Styles rules in CSS files can be written without vendor prefixes (they are prefixed at build time with 'autoprefixer' PostCSS plugin).

Browser compatibility

Code is transpiled to ES5 thanks to babel and the intended compatibility is Firefox 21 / Chrome 23 / IE11.
