CSS Variables vs Preprocessors: Which Should I Use?

What are CSS variables and how do they differ from preprocessors?

CSS variables, also known as custom properties, allow you to store values in a way that can be reused throughout your CSS. Preprocessors like SASS or LESS, on the other hand, extend CSS with features like variables, nesting, and mixins, but require a compilation step.

Can you give me an example of how to use CSS variables?

Sure! You can define a CSS variable like this: --main-color: blue; and then use it in your styles: color: var(--main-color);.

What are the advantages of using preprocessors over CSS variables?

Preprocessors offer more advanced features like nesting, functions, and mixins, which can help organize and maintain complex stylesheets more effectively.

Are there any performance differences between using CSS variables and preprocessors?

CSS variables are processed by the browser at runtime, which can be more efficient for dynamic styles. Preprocessors require a build step, which can add complexity but may optimize the final CSS output.
