In this chapter, we covered a lot, but sadly we barely scratched the surface of RWD and RESS. Packt has several books on RWD, so if you are interested in learning more, I highly recommend you check out one of them. If you are interested in a further look at RESS, you can check out Instant RESS, Chip Lambert, Packt Publishing.

In this chapter, we also looked at how you can use the JavaScript library to check the user's device browser for certain functionality. This allows you to not only tailor your websites and applications to be enhanced on certain devices, but also offer failovers in the event the visitor's device doesn't support a core feature you make extensive use of.

We then looked at device detection with ScientiaMobile's WURFL cloud PHP library. With it, you can check for specific devices themselves that your users may have. You can load the "Download my App from the Apple App Store" banner to your site and have it show on Apple devices. You can do the same with Android devices...
