thanks @mugisha_alain . As @Gassim points out, there are some limited options for customizing the styling of your DHIS2 instance. In general, we try to use a uniform design system in DHIS2, so that users have a consistent experience when using different apps and when using different DHIS2 systems. You can read more about some of the principles of our design here: https://ui.dhis2.nu/principles/color. We may add themes or other customization options in the future, but this is not in our current development plans. (cc @joecooper )
Where you currently can customize styling
login page:
- in v38.6, v39.5, v40.3: this is customizable via api/files/style (e.g. here is the documentation that Gassim shared, specifically for v40)
- in v41, you can upload a custom template (Settings and configuration - DHIS2 Documentation)
custom apps:
- you can write your own apps and make your own styling choices here. We encourage you to use components from the DHIS2 UI library, but you are free to implement what you want. Some developers choose to write their own custom apps to cover most user interaction with the system. You can also set the landing app to be a custom app from within the settings app (Appearance > Start page)
android
- The android app has supported some limited theming. From your question, I believe you are more interested in web apps, but let us know if you are also interested in styling in the android app.
