As mobile devices have continued to evolve and spread, so has the process of designing and developing Web sites and services that work across a diverse range of devices. From responsive Web design to future friendly thinking, here's how I've seen things evolve over the past year and a half.

If you haven't been keeping up with all the detailed conversations about multi-device Web design, I hope this overview and set of resources can quickly bring you up to speed. I'm only covering the last 18 months because it has been a very exciting time with lots of new ideas and voices. Prior to these developments, most multi-device Web design problems were solved with device detection and many still are. But the introduction of Responsive Web Design really stirred things up.

Responsive Web Design

Responsive Web Design is a combination of fluid grids and images with media queries to change layout based on the size of a device viewport. It uses feature detection (mostly on the client) to determine available screen capabilities and adapt accordingly. RWD is most useful for layout but some have extended it to interactive elements as well (although this often requires Javascript).

Responsive Web Design allows you to use a single URL structure for a site, thereby removing the need for separate mobile, tablet, desktop, etc. sites.

For a short overview read Ethan Marcotte's original article. For the full story read Ethan Marcotte's book. For a deeper dive into the philosophy behind RWD, read over Jeremy Keith's supporting arguments. To see a lot of responsive layout examples, browse around the mediaqueri.es site.

Challenges

Responsive Web Design isn't a silver bullet for mobile Web experiences. Not only does client-side adaptation require a careful approach, but it can also be difficult to optimize source order, media, third-party widgets, URL structure, and application design within a RWD solution.

Jason Grigsby has written up many of the reasons RWD doesn't instantly provide a mobile solution especially for images. I've documented (with concrete) examples why we opted for separate mobile and desktop templates in my last startup -a technique that's also employed by many Web companies like Facebook, Twitter, Google, etc. In short, separation tends to give greater ability to optimize specifically for mobile.

Mobile First Responsive Design

Mobile First Responsive Design takes Responsive Web Design and flips the process around to address some of the media query challenges outlined above. Instead of starting with a desktop site, you start with the mobile site and then progressively enhance to devices with larger screens.

The Yiibu team was one of the first to apply this approach and wrote about how they did it. Jason Grigsby has put together an overview and analysis of where Mobile First Responsive Design is being applied. Brad Frost has a more high-level write-up of the approach. For a more in-depth technical discussion, check out the thread about mobile-first media queries on the HMTL5 boilerplate project.

Techniques

Many folks are working through the challenges of designing Web sites for multiple devices. This includes detailed overviews of how to set up Mobile First Responsive Design markup, style sheet, and Javascript solutions.

Ethan Marcotte has shared what it takes for teams of developers and designers to collaborate on a responsive workflow based on lessons learned on the Boston Globe redesign. Scott Jehl outlined what Javascript is doing (PDF) behind the scenes of the Globe redesign (hint: a lot!).

Stephanie Rieger assembled a detailed overview (PDF) of a real-world mobile first responsive design solution for hundreds of devices. Stephan Hay put together a pragmatic overview of designing with media queries.

Media adaptation remains a big challenge for cross-device design. In particular, images, videos, data tables, fonts, and many other "widgets" need special care. Jason Grigsby has written up the situation with images and compiled many approaches for making images responsive. A number of solutions have also emerged for handling things like videos and data tables.

Server Side Components

Combining Mobile First Responsive Design with server side component (not full page) optimization is a way to extend client-side only solutions. With this technique, a single set of page templates define an entire Web site for all devices but key components within that site have device-class specific implementations that are rendered server side. Done right, this technique can deliver the best of both worlds without the challenges that can hamper each.

I've put together an overview of how a Responsive Design + Server Side Components structure can work with concrete examples. Bryan Rieger has outlined an extensive set of thoughts on server-side adaption techniques and Lyza Gardner has a complete overview of how all these techniques can work together. After analyzing many client-side solutions to dynamic images, Jason Grigsby outlined why using a server-side solution is probably the most future friendly.

Future Thinking

If all the considerations above seem like a lot to take in to create a Web site, they are. We are in a period of transition and still figuring things out. So expect to be learning and iterating a lot. That's both exciting and daunting.

It also prepares you for what's ahead. We've just begun to see the onset of cheap networked devices of every shape and size. The zombie apocalypse of devices is coming. And while we can't know exactly what the future will bring, we can strive to design and develop in a future-friendly way so we are better prepared for what's next.
