Sliders are a common UI design element that allow users to select a value or range from a fixed set of options. Sliders look inviting and user-friendly, but in practice they are difficult to manipulate, especially on touchscreen devices. Sliders should only be used for approximate, rather than precise, values or ranges. Further, limit the slider range, as the wider the range the harder it is to select the targeted value. In fact, if picking an exact value is critical to the goal of the interface, consider a different UI element that allows users to use a tap gesture, rather than relying on press-and-drag gestures (e.g. an input field).
