About the Unit
Pixel (px): A pixel is the smallest visible measurement unit on a digital screen, commonly used to describe the resolution and dimensions of graphical elements and text. In a CSS context, the pixel is an absolute unit, but its perception can vary depending on the device's pixel density (such as on Retina displays). Although it is a fixed unit, the pixel value in CSS is standardized to ensure consistency across devices with different resolutions. For example, an element with 100px width will always render with 100 pixels of width on the screen, but on devices with higher pixel density, the content display may appear sharper. The px unit is widely used in graphical interface design, typography, and other visual properties, being the predominant choice in many web design approaches.
