Yes. If you have been a IONOS customer for a while and set up your website before smartphones and tablets became commonplace, you may have chosen a template that isn't responsive, leading to problems when displaying the page on a mobile device. The consequence: the user has to resort to scrolling and zooming to view the relevant information. Changing to a responsive layout is absolutely no problem, simply choose one of our new templates in the mobile friendly website builder and your page will appear in its new design and is immediately optimised for mobile devices. Only a few of our older web apps may have some complications as they are not yet supported. These may not be displayed after changing to the responsive layout.
