If you want to get super-responsive and create separate layouts for different devices, check out the Responsive Layouts feature. Now you have a beautiful, interactive flipbook that plays well on desktop and mobile devices. If you’d also like to see your flipbook layout scale proportionally to the browser window, use the Desktop Scaling and Mobile Device Viewport Zoom settings found in the Advanced section of the in5 dialog. In wider (landscape) browser windows, a two-page spread will be displayed. In narrow (portrait) browser windows, only one page will be shown. Your flipbook will be responsive by default.
