I had an intro web development workshop. First session was only about HTML. I learnt 3 things I did not know about HTML:

1. Footers don't necessarily have to appear at the end of a section, though they usually do [0]

2. A head element's start tag can be omitted if the element is empty, or if the first thing inside the head element is an element. A head element's end tag can be omitted if the head element is not immediately followed by ASCII whitespace or a comment [1]

3. Self-closing tags (<tag />) do not exist in HTML [2]

Please let me know if you know something else.

For my web workshop, I’m looking for examples of modern websites that use only pure HTML (no CSS or JavaScript), like Richard Stallman’s site (https://stallman.org/).

Do you know any others? Bonus if they’re still actively used in 2025.

If you could change or improve one tool, technology, or process in frontend dev, what would it be, and why?
