Preface

	Web design is responsive design. Responsive web design is web design done right.
	--Andy Clarke, Stuff and Nonsense

Take a straw poll of one hundred users and it is likely you will find that a good proportion have viewed the Internet from a mobile device at some point in the past. Use of these devices to access the Internet has exploded massively over the last few years. This has highlighted the need to design sites that work well on a variety of different devices and platforms.

First coined as a term by Ethan Marcotte back in 2010, responsive web design is the art of designing such sites. A key element of responsive web design is the addition of images and videos. Throughout this book, we're going to take a look at the tips and tricks you need to get ahead in adding responsive media to your sites. We'll see how the lack of a common W3C standard means the field is wide open for different solutions and that catering for different platforms means understanding their limits and making suitable allowances for each type of device.

We'll work through a number of practical examples, with both images and videos, and see the importance of testing both to ensure your content displays as expected on any device. We'll then make use of some of the tips and tricks in several real-world examples, using popular frameworks such as WordPress or Less CSS—you'll see that adding responsive media isn't actually that complicated!

Question is though—are you ready to make a start?
