The responsive layout allows a direct adaptation of the Pageflow to the screen size of any given device. You can check it beforehand in the editor: Click the right edge of the editing window and drag the edge further left.

The display and the font will automatically adapt to the smaller format and instead of a navigation you will see an overview of the chapters. Make sure that you choose the right picture detail for the page. To do this, click on „Files“ and then click onto the blue area with the white frame.
