What are advanced CSS preprocessors and how do they work?

Advanced CSS preprocessors like SASS and LESS extend CSS with features like variables, nesting, and mixins, making stylesheets more maintainable.

Can you explain how variables work in SASS?

In SASS, variables are defined using a dollar sign, like $primary-color: blue;, and can be reused throughout your styles.

What are mixins and how do I use them?

Mixins are reusable blocks of styles in SASS. You define them with @mixin and include them in your styles with @include.

Are there any performance benefits to using preprocessors?

Yes, preprocessors can help reduce redundancy and improve organization, which can lead to better performance in larger projects.

What tools can I use to compile SASS into CSS?

You can use tools like Node.js with npm packages, Gulp, or Webpack to compile SASS into CSS.
