To modify the body, go to the menu App>General>Header+Body>Body tab.
The Body refers to the background part of the app. It is fixed regardless of the section or page displayed, and includes the background color and margins of your application.
Do not confuse it with the background of each section, keeping in mind that the first section corresponds to the home page.
Always consider adding a color, even if if you choose to use a background picture, because it is also used for "Pull to refresh".
The formatting for the background image is:
- 1242 X 2208 for iOS and Android smartphones
- 1536 X 2048 in portrait and 2046 X 1536 for landscape for iPad if you are subscribed to the Advanced offer.
When you click on Library, you will have access to the Unsplash gallery (which is licensed under Creative Commons Zero). Feel free to use these photos, they are free and beautiful.
Keep in mind that the color or background picture should highlight your content, but not distracting, so avoid flashy colors.
If you add a color and a background picture, the picture will override the color.
The color of the separator will affect all sections of your app.
