Horizontal scroll refers to a user interface design feature that allows users to move content left or right, rather than the traditional vertical scrolling. This is commonly used in websites and applications to display images, galleries, or long lists of items in a compact format. Users can swipe or click arrows to navigate through the content horizontally. This design is particularly useful for mobile devices, where screen space is limited. It enhances user experience by allowing quick access to additional content without overwhelming the screen. Examples of horizontal scroll can be seen in image galleries, social media feeds, and product showcases.
