I didn't found in "EDITOR" tab in wordpress with theme 'HOW to Format text as Heading / Truly heading in HTML" I check the front page in Page Source just know as text NOT H1, H2 or H3.
In Editor tab just Found (Under Font Box) : Normal, Bold, Italics, etc. How to Format the text content as H1, H2, h3?
This need for SEO. Thanks
