Fixed footer design reveals a persistent bottom section as the user scrolls, often creating a layered effect where page content slides away to uncover the footer beneath. This technique turns the footer from an afterthought into an architectural design feature.
The footer is given a fixed or sticky position at the bottom of the viewport, while the main content sits on a higher z-index with a solid background. As the user scrolls past the content, the footer is progressively revealed, creating a natural parallax-like transition.
The footer needs to work as a standalone visual composition since it will be fully visible at the end of every page. Height must be carefully managed for different screen sizes, and the reveal transition should feel smooth to avoid jarring layout jumps.
