Pixel (px)
Definition: A pixel (short for picture element) is the smallest unit of a digital image or graphic that can be displayed and represented on a digital display device.
History/origin: The concept of pixels dates back to the early days of television and computer monitors. In modern web standards (CSS), a pixel is defined as 1/96th of an inch.
Current use: Pixels are the absolute standard for web design, screen resolution, and digital photography.
Inch (in)
Definition: An inch is a physical unit of length. In digital CSS standards, 1 inch is mapped to exactly 96 pixels.
