Working at night in a light interface can be strenuous and cause eye strain. Starting from version 6.3, ONLYOFFICE Docs support a dark theme and two light ones.
The dark theme colors vary from black to light-gray providing a comfortable interface for working at low-light conditions.
To enable the dark theme,
- go to the File tab,
- open the Advanced Settings section (in the Spreadsheet Editor, select the General subsection),
- choose the Dark theme in the Interface theme section,
- click the Apply button at the bottom of the page.
Now you are all set to continue working comfortably.
