A Range Slider is a user interface element that allows users to select a value or a range of values from a continuous scale. It typically consists of a horizontal or vertical bar with a movable handle that users can drag to adjust the value. This tool is commonly used in applications for settings like volume control, brightness adjustment, or filtering options. Range sliders are beneficial because they provide a visual representation of the available options, making it easier for users to understand their choices. They can also enhance user experience by allowing for quick adjustments without the need for typing or entering numbers manually.
