Webregistration style sheets, where?

Hi there,
using the registration plugin, I would like to change the look of the webregistration page.
Where do I find the .css files and/or the produced webpage to change the necesary style sheet settings ?

I checked in the plugins folder, but there is nothing.
Could someone point me in the right direction ?
Thank you.

The plugins each have their own source repository. The repo for the registration plugin is at https://github.com/igniterealtime/openfire-registration-plugin

That’s where you’ll find those sources!

thank you for the link.
Unfortunately I don’t have any development environment to work with the source code to make the necessary changes, nor do I have the know-how.
