Which languages extend CSS with features like variables, nesting, and mixins and are commonly used with modern frameworks?

• A. HTML
• B. SQL
• C. LESS & SASS
• D. Python

Answer: (C)

Extending CSS with features like variables, nesting, and mixins is what CSS preprocessors such as LESS and SASS deliver. These tools let you write more maintainable and expressive styles: variables let you store colors or sizes in one place, making updates easier; nesting makes the stylesheet easier to read by aligning the structure with the HTML; mixins let you reuse common style blocks across different selectors, often with parameters for flexibility. They ultimately compile to standard CSS that browsers understand, and they fit smoothly into modern frameworks because build systems can process them as part of the development workflow (webpack, Vite, etc.). HTML, SQL, and Python don’t provide these CSS-extending features—HTML is markup, SQL is for data queries, and Python is a general-purpose language.
