Mobile Web Development Strategies

Mobile devices have come a long way in the last few years. As powerful as their desktop counterparts, mobile devices are profoundly different with touch screens, GPS, accelerometers, cameras, and other sensors, not to mention smaller screens. So many differences demand an entirely different experience. We then have the challenge of bringing those designs to life in a sustainable, maintainable, and effective way. We use several key strategies including device detection, progressive enhancement, and responsive design.

Device Detection allows the web server to know which particular device is being used, and to serve up an entirely different web page for that device. Going to the same web site could give you something completely different whether you are on your laptop, iPad, your brand new Android phone, or that old phone from several years ago that allegedly has Internet access. You could build one website for all, but chances are it would only look good on one of these devices. To make it look good on all devices, one must View More on what they must instruct their graphic designer to do on the website design. Device detection lets you target each one separately, for its own unique experience. Not only can you target all mobile devices globally, but you can actually target each specific type and version, from iPhone 3 to Blackberry 6.

Device detection by itself has a major drawback. There are hundreds of possible devices out there, making it costly to build corresponding websites that would be difficult to maintain. Responsive Design is an alternative to this. One website is created that morphs according to the device’s screen width. For instance, a desktop may show a three-column-wide layout, whereas these columns would be stacked one on top of each other for mobile. Responsive design works great for static content. It starts to show some limitations with rich web applications.

Among the many mobile devices out there, screen resolution is only one of the differences. Rich web applications require the use of javascript. Progressive Enhancement checks for javascript support, and if found, adds extra style and functionality that only javascript can give. Older phones will get a basic experience while newer smartphones can utilize modern technology.

So which of these strategies is the best one? Well, that entirely depends on what you’re trying to build, and you don’t have to pick just one strategy. You could use device detection to send the user to a mobile version that uses progressive enhancement, but this is just one possibility.
