What is @property in css
@property in CSS is a powerful feature that allows you to define custom properties, similar to variables in programming languages. These custom properties can be used to store and reuse values throughout your CSS stylesheet, making your code more modular, maintainable, and easier to customize.
Key features of @property:
- Custom property definition: You can create custom properties with a unique name, starting with a double hyphen (--).
- Syntax specification: You can specify the expected data type for the property's value, such as <color>, <length>, <number>, or <string>.
- Initial value: You can set a default value for the property.
- Inheritance: You can control whether the property is inherited by child elements.
