WHAT IS MAKE IT RETINA?
This plugin does all the necessary code to make your site compatible with the retina display. Automatically. No need to restructure the entire website And it is super easy to use.
1. Make sure you have the jQuery library included in your website; 2. Include the Make It Retina plugin; 3. Use this -> $.makeItRetina(); 4. You’ re done!
Works only when it detects the retinal display, so the site does not weight for users with standard screens. Replaces all the images with the respective high-resolution version without having to specify the size or “do things”! It also works with backgrounds!
