A CSS navigation bar, or navbar, is a key interface element in web design that provides navigation links or menus to help users browse different sections of a website. It's a visual guide that enhances user experience by allowing easy access to various parts of the site.
Layout Options: Navigation bars can be positioned either horizontally across the top or vertically along the side of a web page.
Navigation Links: The menu contains links to various pages and sections of the site. These links can be styled as buttons, text, or icons.
Dropdown Menus: Navigation bars can include dropdown menus that display additional links or options when a user hovers over or clicks on a menu item.
Styling: CSS allows designers to customize the visual elements of the navigation bar, including colors, fonts, borders, and hover effects, to create a cohesive and visually appealing design.
Responsive Design: Modern navigation bars are often designed to be responsive, meaning they adapt to different screen sizes and devices, ensuring usability on both desktop and mobile platforms.
Interactive Effects: CSS can add interactive effects to navigation elements, such as changing the link color on hover or click, or highlighting the current page.
