glad you worked it out..
One small advice i want to give you..
There are two places where I add my own custom css or even javascripts..
Firstplace = Customizer
Second pl. = Inside cornerstone(within the page im editing) 🙂
Sometimes I like to place my custom code within the page it self , so it wont target other pages…

And since im in a happy mood. Checkout the responsive text options there. It will make your life much easier when creating your responsive web 🙂
Hope this helps
