In this talk we’ll look at how PostCSS is being used to build a variety of CSS tools; from linters to minifiers and everything in-between. I’ll show how you can use PostCSS to make your own tools. Tools that address your specific needs. In the second half of the talk, I’ll introduce stylelint, a modern CSS linter powered by PostCSS. I’ll outline a few of its features, how it can improve code quality, and how it can be configured to support your choice of CSS methodology (BEM, CSS Modules etc).

A brief run through a few ways of handling flexibility when it comes to patterns and components: modular architectures are hard and defined patterns need to express the right level of flexibility not to defy the point of a pattern library at all.
