You can add expressions to media type to check for certain conditions and apply different stylesheets. For example, you can have one stylesheet for large displays and a different stylesheet specifically for mobile devices. It is quite powerful because it allows you to tailor to different resolutions and devices without changing the content. Continue on this post to read the tutorial and see some websites that make good use of media queries.
