When should I use mixins in CSS?

What are mixins in CSS and when should I use them?

Mixins in CSS are reusable styles that can be included in other styles. You should use them when you have a set of styles that you want to apply to multiple selectors.

Can you give me an example of a mixin?

Sure! A simple mixin could be a set of styles for a button, like this:

@mixin button-styles {
  background-color: blue;
  color: white;
  padding: 10px 20px;
  border-radius: 5px;
}

You can then include this mixin in your button classes.

Are there any downsides to using mixins?

Yes, one downside is that they can lead to larger CSS files if overused, as they duplicate styles. It's important to use them judiciously.

How do mixins differ from functions in CSS preprocessors?

Mixins allow you to include styles, while functions return values. Functions are used for calculations or returning specific values, whereas mixins are for style reuse.
