Sass
Sass, which stands for Syntactically Awesome Stylesheets, is a powerful and popular CSS preprocessor. It extends the capabilities of standard Cascading Style Sheets (CSS) by introducing features commonly found in programming languages, such as variables, nesting, mixins, and functions. This allows web developers and designers to write more maintainable, reusable, and efficient stylesheets. Essentially, Sass code is processed by a program and compiled into regular CSS that web browsers can understand and use to style HTML elements. This makes the process of styling web pages more streamlined and organized.
