👉 The Fluid format is a modern, flexible markup language designed for creating dynamic and interactive content, particularly in web development. It allows developers to define content structures that can adapt to various screen sizes and devices, ensuring a consistent user experience across different platforms. Fluid uses relative units like percentages, viewport widths, and ems to size elements, enabling content to scale proportionally. This approach simplifies responsive design by reducing the need for complex media queries and ensuring that layouts remain fluid and adaptable, making it easier to maintain and update web applications.
