An intranet implemented with the responsive design technique enables employees to access all intranet content on any mobile device or computer. A responsive-design intranet (or public-facing website) has only one codebase but typically has different user experiences for desktop and smaller-screen mobile displays, perhaps a third UX for tablets, and possibly even more user experiences for other devices and screen sizes. Since designers are able to choose how and where the content and features should appear on each device, a responsive intranet can create the best possible UX for employees no matter which device they are using.
