SASS - A powerful preprocessor for CSS

SASS (Syntactically Awesome Style Sheets) is a preprocessor scripting language that is interpreted or compiled into standard CSS. It extends CSS syntax, providing features like variables, nesting, inheritance, and many more, making the front-end development process more efficient and organized.

Why use SASS?

• Code Reusability: SASS allows the use of variables, mixins, functions, and parent selectors, which makes the CSS code more reusable and less repetitive.

• Modularity: SASS supports modular CSS architecture through partials and imports, making it easy to break down CSS code into smaller, more manageable files.

• Productivity: SASS speeds up the development process by reducing the amount of code needed to write CSS, allowing for faster prototyping and development.

• Maintainability: SASS provides a more organized structure for CSS that is easier to maintain and update, reducing the risk of errors and increasing the scalability of projects.
