CustomPress styling on the front end

Hi guys!
Sorry, I don't see CustomPress in the drop down list.
I am having trouble styling the CustomPress plugin in the front end when using the [custom_fields_input] shortcode.
I've tried putting the shortcode in a responsive tab, box, and well (using other another shortcode/plugin) as well as trying it as a sidebar widget--but nothing seems to work. It puts the fields at 100% width no matter what. Am I missing something?
I also don't see Directory or Classifieds in the support list or the plugins list on the website. I hope this doesn't mean that the 3 of these plugins are going away too? I am relying heavily on these plugins :slight_frown:
Thanks for any help with this!!
