Link protocols
relative link protocol
Text fragments
href="#" scrolls to top
href="" reloads the page
href="." reloads the page and remove hash and search strings
href="?" reloads the page, remove the hash and search strings but preserve the query symbol.
href="data:" handle data URLs
href="video.mp4#t=10,20" for media fragments (support is not there yet)

A modal is a small view in the window: this view makes the rest of the content inert.

It makes HTML accessible

See their events https://html.energy/events.html

There are many methods that break performance and accessibility such as dynamic css classes and div and span soup.

Topics adressed from the outline:

1. It’s not just bad HTML – it’s meaningless markup
2. Semantic rot wrecks performance
   1. Big DOMs are slow to render
   2. Complex trees cause layout thrashing
   3. Redundant CSS increases recalculation cost
   4. Autogenerated classes break caching and targeting
   5. Animations and the compositing catastrophe (with properties triggering the layout engine)
   6. Autogenerated classes break caching and targeting
3. Semantic tags can provide layout hints
4. (AI) Agents are the new users and they care about structure
5. Structure is resilience, isn't optional

Likewise, content-visibility: auto is one of the most underrated tools in the modern CSS arsenal. It lets the browser skip rendering elements
that aren’t visible on-screen – effectively “virtualising” them. That’s huge for long pages, feeds, or infinite scroll components.

and I didn't know about the contain CSS property.

contain: layout; tells the browser it doesn’t need to recalculate layout outside the element.
will-change: transform; hints that a compositing layer is needed.
isolation: isolate; and contain: paint; can help prevent visual spillover and force GPU layers.

Structurally speaking, then, a paragraph is a group of related inline elements. In this case, inline words, but it could also include any of the items described as “phrasing content"

<hgroup> issu the tag to use for heading with multiple inline content.

Interesting comment about email development: we can do pretty much everything but the developers have to rely heavily on progressive enhancement.

A valid minimal HTML page

Being messy with class names :)

A points on many HTML tags (aside, mark, section, hgroup, video, progress, base): how to use them. Many good tips or rules to follow.
The CSS @import rule, [attr$=value] is a CSS selector for suffix values, box shadows with inset, cursor: zoom-in

Translated pages with <link rel="alternate"> and hreflang

Some usages such as HTML in script to reuse them as <template />, gpt or instappaper_ignore class names

The web is big and messy and bloated, and there are lots of reasons to be pessimistic about the state of modern web development – but there are also lots of people doing cool and interesting stuff with it.

There’s a taste of “commercial frontend development” being less interested in shipping HTML that is valid and error-free than is our community of frontend developers.

There is few talks about HTML conformance, valid HTML, HTML validation or standards compliance.

Including templates in HTML directly could be a great feature. Many frameworks are already used for it.
