A button is a small, typically round object used to fasten clothing or accessories. It is usually made from materials like plastic, metal, or wood and features a hole or shank for sewing onto fabric. Buttons come in various sizes, colors, and designs, making them both functional and decorative. In addition to clothing, buttons are also found on electronic devices, such as remote controls and computers, where they serve as controls for various functions. These buttons can be physical or touch-sensitive, allowing users to interact with the device easily.
