uncss VS astroturf

I've only used it once but it did the job (NOTE: Plain HTML, plain CSS, no build pipeline. So YMMV)

PurgeCSS analyzes your HTML and internally keeps track of which selectors are being used or not. PurgeCSS actually analyzes other types of files besides HTML for selectors, such as template files and JavaScript. This feature is what makes PurgeCSS different from a similar solution, UnCSS, and related to a 'predecessor' solution called PurifyCSS. More on both of those later on.

In the process of trying to figure out how to remove the unused code, I found out about UnCSS, a tool that removes unused CSS from your stylesheets. It can be installed by running:

Also UnCSS.

CSS-in-JS has been a challenge – we're currently using https://github.com/astroturfcss/astroturf which seemed the simplest zero-runtime-cost option back when we were looking, but the library is starting to feel a bit under-maintained (if the author of Astroturf reads this, we love your work and will do whatever we can to support you in it!). But it's worked well for us over the last 2 years.

Happy to share a component example. We also use a small library for managing CSS classes in a typed fashion, which can also be used by our UI test code to target various elements. So that does add a bit of cryptic boilerplate, but the repo README has an example component with syntax highlighting:

On the other side of our titular question is styled-components. While I'm talking about styled-components specifically, the topics and concepts here apply to any CSS-in-JS provider (e.g. emotion). There is a smaller CSS-in-JS library called astroturf that aims to give the developer the best of all worlds, so the limitations I'll discuss later on don't apply there. But be careful with smaller projects/ones that claim you can have it all! You are wading through uncharted territory :)
