It corrects and cleans up HTML and XML documents by fixing markup errors and upgrading legacy code to modern standards.

A complex challenge as the official standards are implemented in few websites.
Guesses have to be made.

Use emojis as html tags.

It has more impact than "semantic HTML" but it they share common goals.

For papers submitted since the 1st December 2023

HTML is not replacing PDF but will be an additional format available for arXiv users.

The goal is to convert all papers on arxiv to HTML files.
It will moreover allow easier analysis through HTML parsing.

The values of HTML are not exactly the ones of HTML first.

The author recommends to include instead:

• HTML that is actual HTML, i.e., that is valid (common sense, until you start checking)
• HTML that makes full use of HTML features, i.e., that’s not XHTML–HTML
• HTML that is used according to purpose (aka semantic HTML)
• HTML that is accessible

Trusted types are interesting indeed. They won't fit all cases though: what happens if I want to insert HTML? These are cases though, and the majority could use these.

Source of markup ghosts:

1. proprietary markup introduced by browser vendors
2. specs which didn*t see uptake like HTML3
3. use case specific markup on devices like WebTV or early smartphones

Some old tags:

• <audioscope> to display the sound over time. A demo https://www.youtube.com/watch?v=tM7YVhar2Dg
• <au> for authors
• <blackface> for double-weight boldface... in HTML 🤡
• <center> oh shit
• <font> and color attributes
• dingbat attribute to embed emojis, extended unicode entities, icon fonts and custom things. Now it is used as < for example and does not rely on the attribute anymore.
• <multicols> ....
• <person> in HTML 3, but it opens the door for so many other tags. Now instead we can rely on <a rel="author"> or with me

and more

It can be a meme: instead of talking about semantics, UX is trendy and can be used as trendy shit word instead.
UX HTML is more accessible, less error-prone, more maintainable because it uses the right tags and attributes. Yes it is semantic at the end.
So UX of HTML matters.

Let's take a look at how to spin up a simple Node server and use custom elements as templates in three popular formats

As always it depends of the need.

2. The extension suggests how to make it HTML 5 compliant and in "no-quirk" mode

Great explanation of the rel attributes that provide:

• information to the resource linked
• behaviors while navigating
