Change theme and layout

The Theme & Layout settings in the configuration window include options to change the default appearance of the app. For example, you can choose from light or dark mode, apply your organization's shared theme settings (colors and logo, if applicable), or use custom CSS to keep your app on brand.

Most apps also include a set of predefined themes to style the app by changing the background and text colors used for app elements, such as the header, panels, and buttons. You can customize the theme by defining your own color scheme and selecting from a list of available fonts. When you choose custom colors, the contrast ratio for font color and background color is validated for accessibility standards, which require a minimum contrast ratio of 4.5 to ensure text legibility. A warning message informs you when the contrast ratio is insufficient. You can also upload an image to include a custom logo in the header with an optional hyperlink. (Only HTTPS URLs are supported.)

Use the Position manager setting, when applicable, to move and reposition the map tools to create an intuitive experience for the app. Use the button next to a tool name to drag it to a different corner or to change the order of buttons grouped in a corner. Tool locations in the app preview update to match the locations that you choose in the grid.
