There's been a lot of discussion abut CSS-in-JS and all the benefits it gives. It might have its place in Javascript applications, but what if you want to reuse your CSS across multiple websites? I'll talk about why plain old CSS and preprocessors are still relevant and why you'd still want to use them on your project.

In this talk, I'll go over:

* Why CSS-in-JS isn't the answer for every scenario

* A basic introduction to BEM and how to use it in your design system or website

* Why preprocessors such as Sass still have a place in the front-end development world

* What makes the 'cascade' in Cascading Style Sheets so useful

You will come away from this session knowing why CSS and preprocessors are still relevant today and how you can implement more modern CSS practices to your design system or website.

This session assumes a basic knowledge of CSS and basic understanding of modern front-end development practices.
