Shadow DOM: fast and encapsulated styles – Monica Dinculescu

Monica explains how Shadow DOM could be the perfect answer for scoping CSS:

We didn’t have style encapsulation, so we started naming things “the right way” with BEM, so that we didn’t accidentally stomp over each other’s styles. We wanted to be able to author CSS from inside a JavaScript component, so we started using CSS-in-JS. We needed all these tools, because “the platform” (read: the browsers that be) wasn’t there, and building these tools showed that there was a need to move forward. For style encapsulation, Shadow DOM is the platform moving forward.

Although, in a way, Shadow DOM is also another flavour of CSS-in-JS:

Before you complain that using a Shadow DOM and Web Components means that it absolutely requires JavaScript: this is true.

There’s also a corresponding tutorial on custom elements

I really hope that this is the kind of usage we’ll see for web components: enhancements for the browsers that support them without a good ol’ fashioned fallback for older browsers.
