You can make a user control that will wrap Generic Content and will add div
with a specific class name around Generic Content. So you will be able to style Generic Content differently when inserted through that control as you write more specific CSS rules in your site theme.
I have attached a sample control that you can use. So copy this control to your project. After that open web.config and find toolboxControls
section. Add the control to page toolbox like that:
|<add name="Quote Box" section="Most popular" url="~/UserContrls/QuoteTextGenericContent.ascx" description="A quote text generic content box." />
Make sure you have set the right url to the control.
After that, "Quote Box" control should appear in the "Most popular" control section along with Generic Content, Image and Images Gallery.
I have set class name QuoteText
to the div that wraps the Generic Content. You can change it to whatever you want in QuoteTextGenericContent.ascx
All the best,
