What's the difference between screen resolution and viewport size?
Screen resolution is your monitor's total pixel count (e.g., 1920×1080). Viewport size is the browser's visible content area, which is smaller due to toolbars, scrollbars, and window borders.
What is device pixel ratio?
Device pixel ratio (DPR) indicates how many physical pixels represent one CSS pixel. A DPR of 2 (common on Retina displays) means each CSS pixel is rendered with 4 physical pixels for sharper images and text.
