I'm new to wordpress, but I'm a pretty competent developer. I'm trying to nail down what my client can do to their site. My idea was to create some special 'blocks' for them, which provide the page sections they need with minimal editing requirements.
I know you can create custom blocks with a plugin, but can I create them as part of a theme? If so, can anyone provide me with a link to some helpful information about how to do it?
How would one remove the custom block when the theme is deactivated?
Thanks in advance.
