Brett Jankord – Cross Browser Retina/High Resolution Media Queries. Fantasai, Ben Frain, and Peter Gasston have all written about this topic before, though I still see a lot developers using verbose media queries for retina/high resolution displays so I figured I would write up my own post. Most developers are currently writing retina/high resolution media queries similar to the examples below: This media query example is from 37signals article on retina images and scss. It is based on the one in Thomas Fuchs’ Retinafy book but, it has been modified to define the Google Nexus 7 with it’s 1.3 pixel ratio as a retina-capable device. @media (min--moz-device-pixel-ratio: 1.3), (-o-min-device-pixel-ratio: 2.6/2), (-webkit-min-device-pixel-ratio: 1.3), (min-device-pixel-ratio: 1.3), (min-resolution: 1.3dppx) { /* Retina-specific stuff here */ } Chris Coyier has a retina display media query example that looks like this: What’s wrong with the above solutions Nothing really, though they could be a lot cleaner.
IE is using standards, this is new Update Opera Mini. Retina Images. Retina.js | Retina graphics for your website. How it works When your users load a page, retina.js checks each image on the page to see if there is a high-resolution version of that image on your server. If a high-resolution variant exists, the script will swap in that image in-place. The script assumes you use Apple's prescribed high-resolution modifier (@2x) to denote high-resolution image variants on your server. For example, if you have an image on your page that looks like this: <img src="/images/my_image.png" /> The script will check your server to see if an alternative image exists at this path: "/images/my_image@2x.png" How to use JavaScript The JavaScript helper script automatically replaces images on your page with high-resolution variants (if they exist). Place the retina.js file on your server Include the script on your page <script type="text/javascript" src="/scripts/retina.js"></script> (put it at the bottom of your template, before your closing </body> tag) That's it!
