When I add pages, I have the headlines in regular font-weight, but sometimes I leave a headline with bold font weight by mistake.
Is there a way to give all the headlines in the article the same font weight? So it won’t matter what I choose in the editor (bold or regular)
But when I use the bold option in the editor, will it override it?
And I need to create it for every headline right? H1 H2 H3 etc?
Yes and Yes.
But please note, in doing this means that the Editor Bold option for Headings is effectively now defunct. So if you want to use the bold ( strong ) style its going to get overwritten by those new styles.
