When should I use mixins in CSS?

Mixins in CSS are useful when you want to reuse a set of styles across multiple selectors. They help keep your code DRY (Don't Repeat Yourself). You should consider using them when you have common styles that need to be applied in different places.

Can you give me an example of a mixin?

Sure! Here's a simple example of a mixin in SCSS:

@mixin border-radius($radius) {
  -webkit-border-radius: $radius;
  -moz-border-radius: $radius;
  border-radius: $radius;
}

You can use this mixin like this:

.button {
  @include border-radius(10px);
}

Are there any downsides to using mixins?

Yes, while mixins can reduce code duplication, they can also lead to larger CSS files if overused, as they generate additional CSS rules. It's important to use them judiciously.

What are some alternatives to mixins?

Alternatives to mixins include using CSS variables for reusable values, or leveraging utility classes in frameworks like Tailwind CSS. These can help maintain a clean and efficient stylesheet.
