👉 The xHTML Fluid is a CSS property designed to create flexible and responsive web layouts by allowing content to adapt to different screen sizes and resolutions. It works by setting a container's width to a percentage of its parent element, typically 100%, and using `max-width` and `min-width` properties to define boundaries. This ensures that the content within the container scales smoothly across various devices, from large desktop monitors to small mobile screens. The Fluid property is often used in conjunction with media queries to fine-tune the layout for specific breakpoints, ensuring a seamless user experience across all devices.
