Meetings[1]: OOCSS

Last week we met for the first meeting about frontend development thematics. Luca Milan’s objective was to explain the OOCSS (Object Oriented CSS) approach.


How do you scale CSS for thousands of pages? Object Oriented CSS is an answer. It’s an approach for writing CSS that’s fast, maintainable, and standards-based. It adds much needed predictability to CSS so that even beginners can participate in writing beautiful websites.

OOCSS Principles

The OOCSS approach has two main principles

  • Separate structure and skin This means to define repeating visual features (like background and border styles) as separate “skins” that you can mix-and-match with your various objects to achieve a large amount of visual variety without much code.

  • Separate container and content Essentially, this means “rarely use location-dependent styles”. An object should look the same no matter where you put it.
