I have looked through the forum and note this is asked regularly. It would be good to add a switch in the options to remove the title or showni t as desired.
That said I added the following code to the graphene options display->Custom CSS - as recommended in the previous post but I cannot make it work. I have 4 sites where I want to remove the title from the content area
PS - this wordpress theme is one of th best I have found. I have made a contribution based on where my simple sales are at the moment. I congratulate you on your understanding of what your options need to deliver in making the page construct simple
