CSS media queries enable us to filter out devices based on a set of parameters. We have met in the last chapter many parameters that were hard set defined as "yes" or "no". For example, a device could only be a hand held device or not. In this chapter we move away from boolean expressions and move into a rich world of values starting with the width and height expressions. In this lecture we will be introduced to the way to work with expressions.
