Question 1

What is the difference between Less and CSS?

Accepted Answer

Less is a CSS preprocessor that extends CSS with dynamic features: variables (@color: red), nesting (writing child selectors inside parent rules), Mixins (reusable style blocks), and functions. Less files need to be compiled to regular CSS for browser use.

Question 2

Why should I use Less?

Accepted Answer

Less makes CSS more maintainable. Variables let you change global values (colors, fonts) in one place. Nesting shows selector relationships clearly. Mixins let you create reusable style functions, reducing code duplication significantly.

Question 3

Which is better: Less or Sass?

Accepted Answer

Both are similar. Less is built with JavaScript and can compile in Node.js and browsers. Sass uses Ruby/Dart. Less syntax is closer to native CSS (uses @ instead of $), making it easier to learn. Choose based on your project needs.
