Sass and SCSS

Sass (Syntactically Awesome Style Sheets) is a CSS preprocessor that supercharges standard CSS with programming-like features to make stylesheets more maintainable, reusable, and organized. It allows developers to use variables for consistent theming (like colors and fonts), nested rules that logically follow HTML structure, mixins for reusable blocks of styles, and functions for complex operations. Sass code comes in two syntaxes—the original indented syntax (.sass) and the more popular SCSS (.scss), which is a superset of CSS—and must be compiled into standard CSS that a web browser can understand, ultimately enabling the creation of more complex and manageable styling for large-scale web projects.
