CSS @property Rule

Introduction

In this final blog of our CSS series, we will dive into advanced and essential CSS topics that are crucial for modern web design. Let’s cover the @property rule, box sizing, media queries, and the powerful CSS Grid system. These concepts will complete your CSS knowledge, giving you a solid foundation to create responsive, flexible, and well-structured web pages.

The @property Rule

The CSS @property rule is an advanced feature that allows you to define custom properties (CSS variables) with extra controls. It lets you specify the type of value, initial value, and whether the property should inherit its value.

Example: Tooltip on Top:

@property –primary-color { syntax: ‘<color>‘; initial-value: #3498db; inherits: true; }

This example defines a custom property –primary-color that expects a color value. You can now safely use this property throughout your styles, ensuring that it behaves predictably.
