The viewport is the visible area of a web page on your device's screen.
The total width and height of your screen, measured in pixels (px). This is your screen's native resolution.
Color depth indicates how many colors your screen can display. Most modern screens use 24-bit or 32-bit color.
Orientation indicates whether your device is being held vertically (portrait) or horizontally (landscape).
The device pixel ratio shows how sharp your screen is. A higher number (above 1) means you have a high-quality screen like those found on newer phones and tablets.
