The birth and development of Responsive Web Design (RWD) were completely forced by numerous screen specifications (different devices, different sizes, different resolutions...) in now mobile Internet era. Because the traditional fixed layout or fluid layout has been unable to simultaneously cope with desktop computer, laptop, tablet, smart phone, and other devices that support web browsing function.

I think any users who are interested in computers, somewhat get tired of Windows, and want to try some new OS, they may want to begin to reach the mysterious Linux operating system. But if you want to make learning Linux easy, you really need a good book for the level of beginners.
