A responsive website adapts automatically to fit any screen size. It therefore works equally well on small smartphones, on different kinds of tablets and laptops, or on large desktop screens. All your website content can be accessed on each device, though you can of course choose not to display certain information. Too much information on a small screen can be distracting. A responsive site automatically scales all images and adjusts them to the space available. Responsive web design has outgrown its infancy and is increasingly supported by different browsers.
A mobile website is entirely independent of an existing, traditional desktop website, and has its own URL (e.g.: m.domain.com). Design and content are optimised for a small screen, which makes for greater ease of use. A mobile version is an interesting option when you know that visitors are in a hurry and only want to access to a small number of services. So it is important to think carefully about what to omit from your site.
