I know there are some absolute-size units available in CSS. For example, cm, in, mm... But when I use them in my webpage, they are rarely honored. The information about screen physical size and pixel resolution should be available from the EDID - so the browser can access them and calculate the amount of pixels in 1 cm on that particular device. I am talking about ordinary CRT/LED/Plasma screens, not projectors.I want ot use it with mobile devices. A common standard is for every touch target to be at least 9 mm in size. But when I use \[code\]height: 9mm\[/code\] in my CSS code, then the real size is about 3 mm on my HTC Desire HD.So how can I make browsers display elements using the absolute size?
