We have seen that a mobile application can support various touch gestures. With the introduction of new technologies, differences between web apps and native mobile apps are getting close to zero, but not actually zero. One such difference is how click events are handled in mobile apps.

When you click on a button, mobile browsers wait for 300 ms to actually trigger the click event for the button that you have clicked.
