Unlocking the Power of Custom CSS Functions

Ever thought about writing functions directly in CSS? With the rise of custom CSS functions, we’re stepping into a future where styles can be more dynamic, reusable, and flexible than ever before. Let’s break down what CSS functions can do and why they’re a game-changer for modern web development.

?? Theory: Defining and Using Functions in CSS

CSS has always had built-in functions like calc(), var(), and clamp(), but custom functions take things further, allowing greater abstraction and reusability. They bring a programmatic approach to styling, making CSS feel more like a real programming language. There are even pseudo-function, widely named pseudo-classes but I prefer to call them functions as they can get parameters, for example we got: the :not(), :is(), :where(), :has(), :nth-child() which behaviors are slightly different than :hover, :active, :disabled and so on. That's why I prefer to call them pseudo-functions instead of pseudo-classes.

But the CSS ecosystem is about to get a significant update: the ability to create custom function, as we already are able to do with custom properties.

• What are custom CSS functions? They are user-defined functions that allow us to encapsulate logic and reuse values.
• Why are they powerful? Instead of repeating complex calculations or hardcoded values, we can define functions once and use them dynamically across stylesheets.
• How do they compare to preprocessor functions? Unlike SCSS/Less, CSS-native functions can be evaluated in the browser at runtime, meaning they adapt in real-time to changes.
