a few weeks ago in a reply Tom explained how to create a full width post title using the new Elements header features (full width title, above the post content and also above the sidebar).
I searched everywhere but I cannot find that post anymore. Would it be possible to post again the intructions, or link to that post?
I cannot find that post anymore but I think the template tags inside the page hero content you suggested in your reply could be what I was looking for. I will now look into it
