Adjust settings that apply to your entire web map in the Map properties pane. You can enable a background color, preserve the map scale, and configure the time slider for maps with time-enabled data.
Enable a background color
You can use background color on its own or in combination with layer blending. In some cases, especially when using custom basemaps, you may need to set a background color for areas the basemap doesn't cover. The basemap color can be part of the overall thematic focus of the map, or it can be a color that corresponds with organizational themes.
To enable background color, do the following:
- Confirm that you are signed in and, if you want to save your changes, that you have privileges to create content.
- In Map Viewer, on the Contents (dark) toolbar, click Map properties .
- In the Background section of the Map properties pane, turn on the Enable background color toggle button.
The color picker appears.
- Select a color from the color picker, or type an RGB or hexadecimal value into the text box. Click Add to save a custom color and click Remove to remove a saved color. Colors are saved only for the browser session. Click Done when you are finished selecting a color.
The background color changes in real time as you make your color selection. View the background color by zooming out to the map's full extent.
- Save the map.

To preserve map scale, do the following:
