  • The Mobile App Builder and Mobile Card Builder tools can configure both light and dark mode options, allowing users to easily switch between a bright or subdued interface, enhancing comfort, readability, and battery efficiency.

    Light and dark modes

    Light and dark modes are user interface themes that adjust color schemes to optimize screen visibility and comfort.

    Note:
    The option to toggle between light and dark mode will only appear if your instance has both light and dark modes configured.

    Dark mode inverts the typical color palette, featuring a dark background with lighter text and interface elements, which reduces glare and is easier on the eyes, especially in low-light settings.

    Switching between light and dark mode

    To toggle between light and dark modes, select the theme changer button () in the builder tool header to open the appearance picker. Select your desired display mode and your builder tool will refresh in real-time with the new appearance.

    Note:
    Switching to dark mode on Mobile App Builder will automatically change Mobile Card Mode to dark mode and vice-versa.
