| Using CSS-in-JS with Svelte | You don't need to, but you can | Rich Harris | https://twitter.com/Rich_Harris |
CSS is a core part of any web app. By extension, a UI framework that doesn't have a built-in way to add styles to your components is unfinished.
That's why Svelte allows you to add CSS in a component's <style> tag. Co-locating your CSS with your markup means we can solve the biggest problems developers face when writing CSS without introducing new ones, all while providing a rather nice development experience.
But Svelte's style handling does have some limitations. It's too difficult to share styles between components, or apply app-level optimisations. These are areas we plan to address in future versions, but in the meantime if you need those things you can use any framework-agnostic CSS-in-JS library.
For example
Here, we're using Emotion to generate scoped class names that can be used across multiple components:
It's important to note that most CSS-in-JS libraries have a runtime library, and many don't support statically extracting styles out into a separate .css file at build time (which is essential for the best performance). You should therefore only use CSS-in-JS if it's necessary for your application!
Note that you can mix-and-match — you can still use Svelte's built-in CSS handling alongside a CSS-in-JS library.
