What are the best practices for using CSS preprocessors?

When using CSS preprocessors like SASS or LESS, it's important to organize your stylesheets, use variables for colors and fonts, and take advantage of nesting to keep your code clean.

Can you explain how to use variables in SASS?

Sure! In SASS, you can define a variable by using the dollar sign. For example, you can set a color variable like this: $primary-color: #3498db; and then use it throughout your styles.

What are mixins and how do I use them?

Mixins in SASS allow you to create reusable chunks of CSS. You define a mixin with the @mixin directive and include it in your styles with the @include directive.

Are there any performance considerations I should keep in mind?

Yes, it's important to compile your SASS or LESS files into CSS before deploying to production to avoid performance issues. Also, minimize the use of deeply nested selectors.
