CSS variables, or custom properties, allow developers to define reusable style values in CSS, enhancing code maintainability and reducing redundancy. With the use of the -- prefix and var() function, variables can be declared globally or locally, and dynamically modified via JavaScript. This flexibility makes it easier to implement consistent styling across elements, particularly beneficial for projects with numerous similar values. The tutorial aims to provide a practical understanding of CSS variables through four project examples, suitable for developers with basic CSS knowledge.
CSS variables, also known as custom properties, are user-defined values that can be reused throughout a stylesheet, enhancing code maintainability and reducing redundancy.
Unlike traditional CSS properties, CSS variables can be modified dynamically with JavaScript, allowing changes to propagate to all instances using the variable.
