:has has a lot of possibilities with drag'n'drop. Here the developer uses 3 items: mushrooms, potions and .

For example: dragging some items to make parts of the site grow. https://lynnandtonic.com/assets/images/thoughts/case-study-2022-mushroom-header.mp4

Let's create a holiday card generator by learning how to get access to a user's webcam and compose a screenshot.

Great explanation of the rel attributes that provide:

• information to the resource linked
• behaviors while navigating

Create an accessible <marquee> tag

Use <button> if you can count on JavaScript being available, and flipping the switch has an immediate effect.
Use <input type="checkbox" if you want to progressively enhance the control, and flipping the switch will only take effect when the user submits it.

The post explains how.

Ja klar, bei manchen Sachen sollte man das mit ARIA Elementen anreichern, aber bei vielem könnte man es verbessern indem man einfach die richtigen HTML Tags/Attribute verwendet.

Use Cases anzeigen und sie durchsuchen können.

Beispielen:

• Accordion: <details>/<summary>
• <dialog>
• Definitionsliste: <dl> / <dt> / <dd>
• Definition steht im Paragraph <dfn>
• Listen: <ol> / <ul>
• Mehr Kontekt <time>,<kbd>, <abbr>
• Separator zwischen Paragraphen: <hr>
• Abkürzung:
• <address>
• <quote> / <blockquote> / <cite>
• semantische Struktur der Seite: <article> / <section> mit o. ohne Heading / <footer> / <header> / <main> / <aside> / <nav>

A section tag start to be a generic région only when it is labelled. It provides semantics, but nothing else out of the box.

As developer it increase readability and allow to quickly set a specific landmark when needed.

Nice to get it right the first time with a minimal example

box-sizing does not work well with details and summary: it is implemented as shadow DOM in Chrome.

Dedicated to HTML :)

Using radial gradients to create shapes. They are similar in some ways to svgs.

:root {
  overscroll-behavior: none;
}

CSS has gotten easier to write than it is different to write.

• use :is to group multiple selectors such as a:hover and a:focus
• using logical properties instead of marg
• margin-trim can help by removing the last margin child element of a list for example. It is experimental, so Flexbox with the gap property
• aspect-ratio to set only one dimension between the height and the width, while keeping proportions
• .card:has(:hover, :focus) is easier and straightforward than a.card-link:hover > .card
• an easier way to define color palette with --gray-dark: color-mix(in srgb, var(--primary-color), [#fff](https://shaarli.lyokolux.space/./add-tag/fff) 25%);. It is more maintainable!
• ch for managing line lengths; text-wrap: balance is a work in progress (65% of users can use it)

and more with cascade layers, container queries, <selectmenu> and CSS nesting
