Modern UX is a reimagining
The Modern UX has been designed from the ground up to be more intuitive,
powerful, and convenient for today's end users, and whether they connect
to SharePoint on a traditional PC or a handheld mobile device,
the content and performance will be the same.
Modernize your SharePoint sites
The Modern experience in SharePoint is designed to be compelling, flexible, and more performant. Modern makes it easier for anyone to create beautiful, dynamic sites and pages that are mobile ready. Whereas previous versions of SharePoint are more of a platform where power users and developers create sites for their users, Modern SharePoint is more of an app than a sandbox.
What's so special about Modern?
Modern SharePoint includes an updated set of default themes and site designs (or templates) that are responsive and look great on any device. With site themes, you can customize your site's logo and colors to match your brand. Additional branding can be achieved using custom themes or site designs without worrying about something breaking when Modern is updated.
Easy Search & Publication
Communication sites make it easy to create beautiful, dynamic, and performant sites and pages that are mobile-ready and able to distribute to large numbers of people.
Modern search is personal. For example, users see only the results that they already have access to, and other users can’t find documents that are private to users.
