Breeze scrollbar is a custom scrollbar style used in some applications and user interfaces. It is typically seen on Linux systems, especially those that use the KDE desktop environment. The Breeze scrollbar is designed to have a sleek and modern appearance, with a flat design and subtle shading. The Breeze scrollbar is usually a narrow strip on the right-hand side of a window, with a thumb that can be dragged up or down to scroll through the content. The thumb has a rounded shape, and changes color to indicate the position within the content. In addition to the basic scrollbar functionality, Breeze scrollbar may also have additional features like smooth scrolling, touch-friendly gestures, and the ability to adjust scroll speed. These features are often configurable within the application or user interface settings. Overall, the Breeze scrollbar is a visually appealing and functional alternative to the traditional scrollbar design. It is especially popular among Linux users who prefer a modern and customizable user interface.
