Hi!
There were topics like that but it didn’t work for me.
In a Minimal theme you can find something like ‘no-heading’ when you create a page like ‘about us’ in the Dawn theme there is no.. Can anyone help?
I tried in ‘section-main-page.css’ to place ‘display: none’ and it kind of work but when you enter a new page the old page title shows for a second or less and then disappear..
Help!
