Responsive websites are viewed comfortably on any device available. Users of these websites should not need to resize or pan in order to make sense of the content they view. The need for scrolling should also be reasonable for such a website. Many organisations serve entirely different versions of their websites to users using mobile devices and desktop computers.
As many people now view web pages on devices other than desktop computers and on a variety of screen sizes, you can increase the number of people who are aware of your business and develop a good impression of it. One reason for the increase in popularity of alternative devices is that they are very convenient.
