LeSS

Less is a CSS preprocessor that extends traditional CSS with additional features, making it easier to write and maintain styles for websites. It introduces variables, allowing you to store colors or styles for reuse, and nesting, which helps organize your styles hierarchically. Less also supports functions and mathematical operations for calculations. By using Less, developers can create more structured and reusable code, leading to improved efficiency in web development and easier updates to a website's design. Ultimately, it helps manage complex stylesheets better than plain CSS.
