Making Your Website Look Great
Across Multiple Devices
WITH SO MANY different types of devices able to access the web today, how a web page is displayed on those
devices needs to change to best suit the device it is being viewed on. At the moment, the Cool Shoes & Socks page is

they are used.
The CSS3 media queries module ( ) adds many new ways
for you to query attributes of a device on which a page is being viewed and to set up styles specific to those condi-
In this chapter, you use the free Opera Mobile Emulator ( ) to
build and test a Cool Shoes & Socks page that is capable of adapting to varying device conditions.
