This document discusses different navigation designs for websites, including full-screen navigation, drop-down menus, navicons, and scrolling navigation. Full-screen navigation takes over the entire page when clicked and usually has a close button. Drop-down menus reveal subcategories when hovering over a top-level category. Navicons provide an option to hide navigation bars as the user scrolls. Scrolling navigation allows users to navigate between pages by scrolling rather than clicking links.
