More page spam, apologies. Been tinkering with the structure in the background

you should be able to standardize thing like that in a stylesheet or other non-html file that when updated will not spam these updates, then just have all pages load that file as needed. Depending on what you're doing and how of course.

I am not quite sure what you mean. I am updating each post page because, for example, the label that points to a specific place in the JSON changed.

My apologies, I thought you meant the background of pages
