In the HTML section there is a recently created article about “Kinds of HTML content” . However, most of the existing links regarding this concept point to https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Content_categories 
Should those be merged (with attention to the “content categories” links used in almost every HTML article pages)? Is there another angle one might want to cover in this article () which couldn’t be adressed in ?
Thanks for your feedback
