How to see custom theme styles in control panel in FCK Editor

[Andrzej Drozdowski, modificado hace 11 años.]

Hi,
I have developed a theme where I have changed heading styles h1, h2, h3 ... and paragraph font.
This is the only theme used in my portal.

I would like to see these styles when I create or edit a web content in control panel.
What is the easiest way to see the styles from custom theme in control panel FCK Editor.

I am using version 6.0.6

Thanks in advance
Regards
Andrzej
