Split · Sign-in theme
Split
A brand panel in your color with your own headline next to the sign-in form. It sets the side panel HTML, which organization admins can install on Casdoor 4.20.0 and later; before that only a global admin can.

This theme sets custom HTML. On Casdoor 4.20.0 and later an organization admin can apply it; before that only a global admin (an admin of the built-in organization) can, and when anyone else saves it, Casdoor keeps the application's old HTML.
What it sets
| Theme | default |
|---|---|
| Border radius | 10px |
| Form position | Center, with the side panel |
| Custom CSS | No |
| Custom CSS Mobile | No |
| Side panel HTML | Yes |
Everything is on the application's UI Customization tab in Casdoor, so you can keep adjusting it after applying the theme.
Apply it to an application
- Enter the application below, adjust the theme's settings, and copy the JSON.
- In the Casdoor console, open Applications, edit that application, click Import JSON at the top, paste the JSON and click OK.
- Click Save. The sign-in page uses the theme from the next visit.
