SCSS stands for the Sassy Cascading Style Sheets. The more advanced variant of CSS is SCSS. It was created by Chris Eppstein and Natalie Weizenbaum and designed by Hampton Catlin. It is also referred to as Sassy CSS due to its advanced features. It is a pre-processor language that is compiled or interrupted into the CSS. It has a file extension of .scss.
We may add several extra features to CSS using SCSS, including variables, nesting, and many more. All of these extra features may make writing SCSS much simpler and quicker than writing the standard CSS. SCSS may use the CSS code and function. SCSS is entirely compliant with the CSS syntax, though also supporting the full power of SASS.
