• CSS Techniques for Retina Displays
  As many people use their highly portable devices for work and play, device manufacturers seek to enhance their user experience, making their devices simultaneously more powerful and easier to use. Apple gave us a completely new line-up of products that introduced double density pixel screens, creating sharper images on smaller screens. Other device manufacturers are following suit with their own version of high pixel density screens. While this is undoubtedly a boon for consumers and end users, it can present a challenge to web developers and designers to make their websites and apps compatible with such Retina displays. It was then that web developers realized how old fashioned the web is and how websites looked “non-living” on such displays.
