The term Responsive Design describes a web design technique by which a website adapts and changes its appearance depending on the size of the screen on which is displayed to the user. This way sometimes displays less and sometimes more information with the right format to the visitor, by making the appropriate allocation of the available space.
In this way the maintenance of a website for multiple devices is easier because you have one version of HTML code and with the appropriate use of CSS formatting code your website can be updated and displayed in various screen sizes such as mobile phones, tablets, laptops, computers and even smart tvs.
