Frequently Asked Questions

Is CSS nesting supported in all browsers in 2026?
Yes! As of 2026, native CSS nesting is supported in all major browsers including Chrome 120+, Firefox 117+, Safari 17.2+, and Edge 120+. It's safe to use in production.
What is the difference between SCSS and CSS nesting?
Native CSS nesting requires the & symbol for element selectors (e.g., & span {}), while SCSS allows implicit nesting. The converter handles this difference automatically.
Should I still use SCSS?
Native CSS nesting covers most nesting use cases. However, SCSS still offers variables ($vars), mixins, functions, and loops that native CSS doesn't have (though CSS custom properties replace variables).
