Applications developed in HTML/JavaScript/CSS language can be entered into all browsers as long as they are developed once. line distribution. Even if you use traditional apps Store app store channel only needs to "package" the underlying application developed with HTML5 into an App, which is far less expensive in terms of time and capital than Cross-system portability.
