The dramatic growth of mobile traffic has created an urgency for websites to adapt to different screen sizes. Responsive design is the preferred technique for making web content adapt to the device on which it's viewed. This approach ensures that the appropriate content is rendered in an appropriate way on phones, tables, laptops, and any other screen being used.
A corollary to responsive design is the need for performance. Delivering content that's customized for a particular device isn't enough if its delivery is slow and frustrating. Indeed, last week Google announced that websites need to deliver their design appropriately and quickly on mobile devices or they will be demoted in Google's search results.
How can you know if your website matches these standards for adaptive content and speed? SpeedCurve's Responsive Design Dashboard answers both questions in one view.
