CSS Custom Properties vs. SASS: Which Should I Use?

What are the main differences between CSS custom properties and SASS?

CSS custom properties (variables) are native to CSS and can be manipulated at runtime, while SASS variables are pre-processed and cannot change after compilation.

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

Sure! For CSS custom properties, you might define a variable like --main-color: blue; in your CSS. In SASS, you would use $main-color: blue; and then use it in your styles.

Which one is better for large projects?

It depends on your needs. SASS offers more features like nesting and mixins, which can be beneficial for large projects, while CSS custom properties provide flexibility and dynamic styling.

Are there any performance differences between the two?

Generally, CSS custom properties can be more performant in terms of runtime changes, as they don't require recompilation. SASS may have a larger initial load due to its pre-processing.
