Themes designed for the Editor, such as the Twenty Twenty-Three theme, come with various Template Parts (such as a Header, Footer, and Post Meta) and Templates (such as Home, Index, Search, 404) for various pages.
What is the correct way to manage these Templates and Template Parts to reduce the chance of issues when the theme is updated? Is it safe to edit these Template Parts and Templates directly, overwriting the ones that come with the theme? Or should I make copies, edit those, and then use the copies for the various pages? Or is there some other approach that is better?
With a block theme, the user can edit all parts of their website without code
andBy using the Styles interface, users can customize colors and typography for the website and for the blocks
. This is making it seem like I don't need a child theme to safely edit the Templates and Template Parts. That seems to be supported by the Site Editor documentation but it's still not totally clear what happens to edits to a theme's Templates or Template Parts when the theme gets updated.
