Developers should learn CSS Custom Properties to build scalable and themeable web applications, as they simplify style management and enable dynamic theming without recompiling CSS meets developers should learn less when working on large-scale web projects where css maintenance becomes cumbersome, as it enables variables for consistent theming, mixins for code reuse, and nested rules for better organization. Here's our take.
