Custom scrollbars in HTML can enhance user experience on web pages by adjusting the scrollbar's thumb size and appearance.
CSS pseudo-elements like ::-webkit-scrollbar, ::-webkit-scrollbar-track, and ::-webkit-scrollbar-thumb are used to style different parts of the scrollbar.
Custom scrollbars offer improved accessibility and allow developers to tailor UI elements to match the site's design.
By applying specific CSS styles to the scrollbar elements in HTML, such as adjusting widths and colors, you can create a visually appealing and functional custom scrollbar.
