Thanks Weaver. I followed what you did with writing a caption and it work the same on my site. The caption drifts around and does not line up center under the photo until published. After publishing, it lines up under the photo on both the frontend and backend.
As far as the H1, H2 etc. What I meant by, “changing the font and font size of the H1, H2, text etc. was not an issue with pre-Gutenberg WordPress,” is that changing the H1, H2, H3 font size in the classic WordPress was easy.
I also followed you steps with Customizer -> Typography -> Content menu. That does give general control over the fonts and sizes. Thanks! But as your wrote, “You can’t change the font from inside the Block Editor by design of the Gutenberg team.” Hopefully they will change that or someone will develop a plugin. I for one, like to have control over my font and sizes. I’m sure others do as well.
Other than the basic WordPress support forum is there another way to send feedback to the Gutenberg team?
Thanks!
