In this article, you can learn how to create customized themes and use them to change the look of you appsuite installation.

File structure

A theme basically consists of two files located in $APPSUITE_ROOT/apps/themes/$YOUR_UNIQUE_THEME_NAME. These files are described in this and the following sections.


This file can be used to override variables described in the "Variables" section of this article.


This file can be used to define any CSS you like. Before doing this, check, if there really is no variable that can be used to achieve the same thing.

How to activate a theme during development

When creating a new theme, you don’t have it installed with your frontend. In this case you don’t want to go to a complete build of a theme and reinstall it for every change. The trick is to create your theme and overwrite the default theme with it. You can then use the appserver proxy to ship your own version of the UI.

To activate a theme on the backend, you have to add it to the io.ox/core/settingsOptions//themes list.



io.ox/core/settingsOptions//themes/unicorn=Friendship is Magic

to etc/settings/ add a theme named unicorn with the name Friendship is Magic to the list of themes, a user can choose. Find the list in the Settings -> Basic view behind the option Theme.

Theming the login page

The login page is a little bit special. If you don’t use the form login (and provide your own login page), you might want to also theme the login page. Learn here, how to do this.

Best practice

To be really safe, it’s best to only define your own values for the variables shown above. If this really breaks anything, we consider this a bug, please report it [1] in our bugzilla.

Of course, using CSS in style.less file to define your own styles is also possible. Make sure to test your style in such cases more carefully. It is most likely safe to change minor things using this file, but if you plan to change any positions of larger elements, this might break the complete design. So please be careful when overwriting the default CSS rules.
