No and that's the difference Headway made. Wordpress 5 is concerned with the output of the 'content' part of the page. It lets you do what you could with a page builder, but more limited.

Headway is literally like creating the theme without coding anything. You build it out of blocks still but you literally just drew boxes onto the page where you wanted boxes to go (based on column system but CSS grid/Flexbox would be better now) and it would output the theme files for you.

And I'm not talking the page, I'm talking the entire theme. So headers, footers, custom pages, custom loops with custom queries, custom blocks mixed in with content blocks on the same page template to allow users to output content in the right places, same with custom fields etc.

It was incredibly powerful and let you effectively WYSIWYG the function of the site as well as then being able to switch over to the design module and WYSIWYG the design too. Plus managing custom CSS was easy.

Later versions let you draw/build and design in the same step like Elementor and Pagelines do, but those don't give you the same control over the functionality of the theme like Headway did.

As I mentioned, you can get most of the same functions Headway provided through something like Elementor Pro and combining it with something like the Toolset plugins. But those rely on integrating and there are issues (dynamically showing content generated by shortcodes currently broken for instance) which make the whole process much more of a chore.

Headway really was great.
