👉 The sitemap fluid is a responsive design technique used to create flexible and adaptable navigation structures within websites. It involves using relative units, such as percentages or viewport units (vw), to define the positions and sizes of navigation links, menus, and other site elements. By incorporating a base width or height and multiplying it by a fluid value (e.g., 0.8 for 80%), developers can ensure that these elements scale proportionally across different screen sizes and devices, maintaining consistent spacing, alignment, and overall layout integrity. This approach enhances user experience by providing a seamless navigation system that remains accessible and visually appealing on both large desktop monitors and small mobile screens.
