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.

Bonus: Responsiveness and Scaling to the Browser When the export is done, you can choose Open in Default Browser to see your HTML5 flipbook. In this case, choose the Flipbook with Page Peel option from the Page Format menu before clicking OK to export. Alternatively, if you want to customize your export options more, you can choose in5 > Export HTML5 with in5… to export your document instead.
