Flexbox

CSS Flexbox opens a lot of possibility for items positionning. As a project base, this boilerplate provides only the most common (Opinionated :) properties. You can always extend it by custom classes if needed.

SailorCSS ^2.0 provides some SASS placeholders for Flexbox properties. Placeholders are great to keep a Object-oriented CSS codebase without repeating code.
