Hi,
I am trying to use custom CSS but I don’t know why it’s nor working. Let me send you the screenshots.
This is where I want to change the size of the font http://prntscr.com/sesswu
This is where I added the css, from your theme settings: http://prntscr.com/sestas
The css I put http://prntscr.com/sestu6
In the custom css field of wpbakery i used both style (.class-name) and (class-name). Nothing worked.
