Web applications can look like local applications

As Web designers we spend a lot of time trying to make our designs stand out. But sometimes it's better to blend in. And with the CSS system color keywords, you can build Web applications that look like they are actually Windows or Macintosh applications. For example, when you open up Word, it doesn't open in the Microsoft color palette. All the window bars, menus, and so on are in the color palette of your machine. And to be user friendly, Web applications can do the same thing with these keywords.
