Below are a few of my favorite examples of Responsive Web Design, the practice of setting media types allowing the design to scale to adapt to whatever the size of the screen that the user is using.

Device Agnostic Design
An article from Smashing Magazine talks about Device Agnostic Design which is a great future proofing advancement from responsive design. Being device agnostic means that you use your content to set break points, not the device you want the content to display on. This is important because if we spend time developing content for specific devices we are creating the next developer nightmare. There is no way to predict the size or aspect ratio of screens in the future. What happens if you design your site to perfectly fit your favorite tablet only to discover that the next generation of that same device has a slightly different sized screen.

For now, it seems as though developers are at the mercy of hardware makers. All we can do is hope they create some sort of a standard, and quick. In the meanwhile, we’ll have to make design decisions based on the content we want to show. After all, content is King.
