What are advanced CSS mixins and how can I use them?

Advanced CSS mixins are reusable blocks of styles that can be included in other CSS rules. They help in maintaining DRY (Don't Repeat Yourself) principles in your stylesheets.

Can you give me an example of a mixin?

Sure! Here's a simple example:

@mixin rounded-corners($radius) {
  border-radius: $radius;
}

.button {
  @include rounded-corners(10px);
}

How do mixins differ from functions in CSS?

Mixins allow you to include styles directly, while functions return values that can be used within styles. Functions are more about calculations.

Are there any performance considerations when using mixins?

Yes, excessive use of mixins can lead to larger CSS files, which may impact performance. It's best to use them judiciously.
