Is it possible to mutate the DOM directly from HTML, without any JavaScript?
All the ways I know of to mutate a DOM are JavaScript.
Just for broadening general knowledge I want to know if there is any common way to mutate the DOM via HTML itself, without involving any JavaScript (perhaps some internal HTML function that will cause this).

No you can't.
HTML stands for Hyper-text markup language. So it's basically a text that may link to itself or to other texts and that have some styles.
HTML is for providing the structure of the page, whose style (appearance) could be altered by css and in any other way by Javascript. But it's not dynamic (programmable) by itself.
No.
Short Answer
No, it is not possible to mutate the Document Object Model (DOM) via HTML. You can mutate via JavaScript.
Long Answer
The Document Object Model (DOM) is a programming interface for HTML and XML documents. It represents the page so that programs can change the document structure, style, and content. The DOM represents the document as nodes and objects. That way, programming languages can connect to the page.
A Web page is a document. This document can be either displayed in the browser window or as the HTML source. But it is the same document in both cases. The Document Object Model (DOM) represents that same document so it can be manipulated. The DOM is an object-oriented representation of the web page, which can be modified with a scripting language such as JavaScript. (Source: MDN).
