'Sass (Syntactically Awesome Style Sheets)' elevates standard CSS through its preprocessing capabilities. It introduces advanced features like variables, nested rules, mixins, and functions, fostering a more streamlined and modular method for crafting stylesheets.

Sass equips web developers with the tools to create maintainable, reusable CSS code, particularly beneficial for complex and large-scale web projects. This leads to a more efficient development process and results in more structured and organized stylesheet designs.
