Post Author
The current post's author — a byline, with an optional avatar.
The block renders through the post_author element — the same PHP that runs in the page builder, so the front
end is identical either way.
What the sidebar exposes
| Option | What it does |
|---|---|
author_prefix | Text before the name, e.g. “By” |
link_to_author | Link to the author archive |
show_avatar | Show their avatar |
avatar_size | Avatar size |
text_align | Alignment |
text_color | Text colour |
font_size_preset | Text size preset |
Anything not listed stays available in the page builder, and round-trips untouched — the block only writes the values you change, so an element styled in the builder keeps every setting this sidebar does not show.
It renders whatever post it finds itself in, at render time. In the editor that is the post you are editing — so the canvas shows this post's value, which on a new draft is often empty, correctly.
In a Theme Builder template it stands for every post the template serves.
For the card with a description, avatar and social links, use the Author Box block instead.
The block declares core spacing support, so the element's own spacing option is not exposed here —
use the Dimensions panel at the top of the sidebar.
