I am back from a vacation, a cold, and a very long dilemma (of deciding what to code) with... this!
It's a very overly-neat-newspaper coded design, and it can be used as both an article or a book. Essentially, it has a page system for books, and the comments (very extensively) explain how to remove the page-ification to turn it into an article.
It's extremely easy to use and edit:
Change three variables at the beginning of the CSS (the section in the markers) as explained in the comments to change the entire colour scheme
use tags to make things stand out or divide boxes into different sections, as explained in the comments
Also explained in the comments (how very surprising), is how the page and box system works (including the alternating sizes and how to override them)
If I missed anything, rest assured, they're explained in the comments :D
Please don't steal my credits (feel free to add your own, though), and go forth and ✨edit✨
