Daily Software Tips & Tricks

Stop hardcoding hex codes all over your stylesheets. CSS Custom Properties (variables) are natively supported and incredibly powerful because they can be updated dynamically via JavaScript or scoped to specific components. By defining a primary color at the root level, you make global theme changes a breeze. Plus, it makes your code much more readable—seeing var(--brand-success) is way more helpful than staring at #2ecc71 and trying to remember which shade of green that is.

Unlike SASS or LESS variables, these exist in the browser at runtime. This means you can change your entire site's color scheme by simply toggling a class on the body tag or updating a single property value in your dev tools, which is a game-changer for building dark modes.
