In this chapter, we've learned what CSS3 media queries are, how to include them in our CSS files, and how they can help our quest to create a responsive web design. We've also learned how to make modern mobile browsers render our pages in the same manner as their desktop counterparts and touched upon the need to consider a "content first" policy when structuring our markup. We've also learned the data economies that can be made when we use images in our design in the most economical way.

However, we've also learned that media queries can only provide an adaptable web design, not a truly responsive one. Media queries are an essential component in a responsive design but a fluid layout that allows our design to flex between the break points that the media queries handle is also essential. Creating a fluid base for our layout to smooth the transition between our media query break points is what we'll be covering in the next chapter.
