Style Guides, Pattern Libraries, Design Systems and other amenities.
Cristiano Rastelli | @areaweb (

Style guides and component libraries are the new trend in front-end development. Everyone is into "Atomic Design" and "Modular CSS" nowadays. But how did we get to this “hype”, and why? What is a style guide, what is its value and where are the benefits of introducing one in a project? And are them useful only for the web, or can be employed by other platforms too? I'll try to give an answer to all these questions in this presentation – directed to designers, web developers but also iOS/Android/Win developers – and I'll show how our Mobile Web team in Badoo has developed his first style guide and how is using it to catch bugs and create a shared pattern library.

Refactoring CSS Without Losing Your Mind
Harry Roberts | @csswizardry (

Working with CSS is tricky enough as it is; working with legacy CSS can be nightmarish. In this talk, we’ll look at how we decide what to refactor and when; how we can refactor code whilst still shipping features; how to avoid regressions when adding new CSS; how we can avoid the dreaded refactoring tunnels; running new and legacy code in tandem; and a bunch of other neat little tips and tricks.
