What is SCSS?

Purpose

Explain what SCSS is and when it is used.

Audience

This document is intended for junior developers who are comfortable with basic CSS but new to preprocessors.

Definition

SCSS (Sassy CSS) is a CSS preprocessor syntax that adds features like variables, nesting, and mixins to help you write cleaner, more maintainable styles.

How SCSS Works (High-Level)

You write SCSS in .scss files, then compile it into regular CSS that browsers understand. This means you can use helpful features in development while still shipping standard CSS.

Why SCSS is Used

SCSS helps teams keep styles organized, reuse values, and reduce repetition. It is especially helpful on larger projects where CSS can become hard to manage.

Key Takeaways

• SCSS extends CSS with variables, nesting, and mixins
• SCSS files are compiled into standard CSS
• It helps keep large style codebases maintainable
• It is widely used in modern front-end workflows
