Scrollbars

Scrollbars are graphical user interface (GUI) elements that enable users to scroll through a document or webpage that exceeds the size of the window or viewport. They typically appear as vertical or horizontal bars located at the edge of the content area, and users can interact with them using a mouse or touchpad. Scrollbars allow users to navigate through the content by scrolling up or down, or left and right, and can also provide information about the location and size of the content. Some modern interfaces hide scrollbars until they are needed, while others make them permanently visible. Customizable scrollbars are also available for web developers to enhance the visual appearance of their pages.
