In this chapter, we have focused on testing the website by using tools and scripts to ensure its responsiveness on all devices. We have understood the importance of checking possible errors in our implementation by using website tools such as Viewport Resizer, Surveyor, and ScreenFly. Also, we have tested the Opera Mobile emulator by opening websites in the native Opera Mobile browser simulating many mobile devices.
In the next chapter, we will ensure that the cross-browser solution is providing fallbacks. We will learn how to handle older browsers and render the correct design by displaying a graceful degradation.
