What are the differences between CSS variables and Sass variables?

What are the differences between CSS variables and Sass variables?

CSS variables are native to CSS and can be changed at runtime, while Sass variables are pre-processed and cannot be changed after compilation.

Can you give me an example of how to use both?

Sure! For CSS variables, you can define them like this: --main-color: blue; and use it with color: var(--main-color);. For Sass, you would define a variable like $main-color: blue; and use it with color: $main-color;.

Are there any performance differences between the two?

Yes, CSS variables can be more performant in terms of runtime changes since they are handled by the browser, while Sass variables are compiled and do not affect runtime performance.

Which one should I use for my project?

It depends on your needs. If you need dynamic styling, go for CSS variables. If you prefer a more structured approach with features like nesting, Sass might be better.
