title: How can I calculate CSS pixels from resolution?
body: <p>I am making a web application that has some very specific interactivity features that are quite screen size dependent. I have planned to create 2 versions of said features, one for desktop and one for mobile.</p>
  
  <p>This brings the issue of targeting screen size. I've decided to use the Samsung Galaxy Note as the highest screen size I will be supporting for the mobile version of these features. However, for this I need to find out the <strong>CSS pixel</strong> size of this screen.</p>
  
  <p>How can I find this out if I know that the display is 13.46 cm (5.29 in) and 800x1280 px (285 ppi)? </p>
