Customising the CSS

This module uses an IFRAME to render the WIRIS editing interface which a really nice piece of kit functionally but is certainly lacking in its appearance compared to content editing screens that we can provide today courtesy if nice admin themes.

I use the H5P module a fair bit and that does the same - i.e. use an IFRAME too.

The H5P module provides a neat hook that enables us to squirt some CSS overrides into the IFRAME content and I was hoping we might be able to do the same with WIRIS.

Does anyone have any experience with this?

Thanks
