XTypo doesn't look same in browser as editor

The editor view looks very different from what the browser shows using XTypo.

The article is called "Test page" under the menu "About".

Could you help me understand what I may have done incorrectly?

Hi Jchan,
It because you use the different themes for xtypo. So in the editor view, xtypo will use the default theme, but in the frontend it will use the theme you defined in the plugin backend

Thanks, I will review the documentation then to get a better understanding of how to use XTypo
