To perform this check, targetting all possible browsers out there, we will be using following three properties. Example: This example displays an image if it detech touch screen device otherwise image will not display.

There are many strategies to choose from when developing a modern, device independent website nowadays. How should capabilities of the device or browser be determined? Should the presentation logic be server side or client side?

Traditionally, mobile optimization had to happen server side. Over the last couple of years, Responsive Web Design and tools like Modernizr have become very popular. Recently, combination techniques often called RESSwhere optimization is done both server-side and client-side, has become a trend.

Whether we are using regular expressions in JavaScript, Modernizr or a complete device-description repository DDR for server-side detection, the purpose is usually the same: to give users a better experience. This typically happens at two levels:. The challenge is to do this in ways that are both scalable, maintainable and, as much as possible, easy to implement.

For some projects, the cost and complexity of deploying third-party tools on servers is too high.

However, in certain cases when the device cannot be identified on the server side alone notably, in the case of iOS devicesthe JavaScript file will contain a few more checks to determine the device. This is a big deal because this use case is supported neither by sheer User-Agent analysis nor by Modernizr tests.

The size of the returned JSON object will be fairly small, varying from 0.
