Where do you put styles in web components?
I'm assuming that we're using the Shadow DOM here as, to me, that's one of the big draws of a web component: a platform thing that is a uniquely powerful thing the platform can do. So this is about defining styles for a web component in a don't-leak-out...

Making Web Components for Different Contexts

This article isn’t about how to build web components. Caleb Williams already wrote a comprehensive guide about that recently. Let’s talk about how to work with them, what to consider when making them, and how to embrace them in your projects.

Advanced Tooling for Web Components

Over the course of the last four articles in this five-part series, we’ve taken a broad look at the technologies that make up the Web Components standards.

Encapsulating Style and Structure with Shadow DOM

For example, have you seen the way Business Insider provides an article's key points...

This confused me for a bit here so I'm writing it out while it's fresh in mind. Just because you're using a web component doesn't mean the styles of it are entirely isolated. You might have content within a web component that is styled normally along with the rest of your website. Like this:
