+Using `<style global>` will skip automatic scoping for every CSS rule in the `<style>` block. This escape hatch should be avoided if possible but can be useful if, for example, you need to modify styling for HTML elements added by an external library.

 Sass (an alternative to CSS) is also available via `<style lang="scss">`.

It means that you can **focus on styling and not naming.** Local-first approach fits in very well with Astro’s ESM-powered design, favoring encapsulation and reusability over global scope. While this is a simple example, it should be noted that **this scales incredibly well.** And if you need to share common values between components, [Sass’ module system][sass-use] also gets our recommendation for being easy to use, and a great fit with component-first design.
