It reflects ARIA presses state with CSS. Isn't it already built-in ?

I am using it for aria-current.

Should it become a standard layout?

I also started when Flexbox was becoming at thing around 2014-2015.

[I] ... always hope that they learn from our past mistakes and become masters at the basics.

Replace <br> with text-indent: 2em each-line;.

The support for "each-line" is limited though: https://caniuse.com/?search=text-indent+each-line

TL;DR use fluid typography and now uses fluid sizes :)

The idea is to set sensible typographic defaults for use on prose (a column of text), making particular use of the font features provided by OpenType.

Different definition of a UI component, from the minimalistic css one to the SSR full page.

Use cases for CSS display contents: ungrouping elements

• styling generated HTML
• conditional (header) layout
• remove a container
• a grid of photos
• alternating columns
• quote
• footer layouts
• subgrid alternative

CSS display: contents is known to cause accessbility issues when used with HTML tables, headings, buttons, and lists

Also what about the tabbing order?

Use cases for :has:

• .card:has(button:focus-visible)
• .xy-pad:has(.handle:active), .xy-pad:has(.handle:focus-visible)
• We can use :has as a sort of global event listener: html:has([data-disable-document-scroll="true"])
• JS-free darkmode: body:has(#dark-mode-toggle:checked)
• p:has(+ figure): with :has, we can style one element based on another element in a totally different container! See the cool code playground that highlights

:has can be powerful to replace JS with HTML semantics.

I will read it someday :)
