Themes are only available starting with Openmeetings 2.x.

Editing the theme

To modify default theme used by OM

• please open following file in the Git:
  https://github.com/apache/openmeetings/blob/master/openmeetings-web/src/main/webapp/css/theme_om/jquery-ui.css
  Or if you already installed OpenMeetings on your machine at:
  /webapps/openmeetings/css/theme_om/jquery-ui.css
• follow the link next to "To view and modify this theme, visit" text in css comments

The file contains border, background and font color definitions as well as paths to icons that are loaded at runtime.
You can change the theme at runtime and just reload the browser (eventually clear the browser cache) to see updates based on modification in your theme.

All other elements might be styled by modifying CSS files in /webapps/openmeetings/css folder

Creating custom CSS rules

1. open webapps/openmeetings/css/custom.css file
2. add you custom rules
3. restart OM (force reload might be required)
