> The most important thing to take away from the original is that the css unit "px" has no relationship to the actual size of a pixel on the screen Did you read this article? Did you make it to this part? I’ll just finish by going through a few of the explicit claims made in that article and correcting them: [...] 2. The first sentence: “The “px” unit in CSS doesn’t really have anything to do with screen pixels, despite the poorly chosen name.” – this is obviously complete nonsense. The standards authors went out of their way to give browser authors a way to match the “px” unit up to the real-world device pixel > and all the physical units (inch, cm, pt) are defined in terms of the csspixel. Not for print and other high-res devices (like a Retina display). Did you read this excerpt quoted from the CSS spec? For print media and similar high-resolution devices, the anchor unit should be one of the standard physical units (inches, centimeters, etc). For lower-resolution devices, and devices with unusual viewing distances, it is recommended instead that the anchor unit be the pixel unit.
