CSS variables, also known as custom properties, are a feature in CSS that allow developers to store values in variables. These variables can be reused throughout a stylesheet, making it easier to maintain and update styles. CSS variables are defined using the --variable-name syntax and can store various types of values, including colors, lengths, and strings. They are particularly useful for creating dynamic and responsive designs, as they can be easily updated and adjusted without modifying multiple style rules. CSS variables can be scoped to specific elements or the entire document, and they can be inherited by child elements. This feature was introduced in CSS3 and has since been widely adopted in modern web development.
