28c3: The Science of Insecurity - YouTube

I understand less than half of this great talk by Meredith L. Patterson, but it ticks all my boxes: Leibniz, Turing, Borges, and Postel’s Law.

Why `details` is Not an Accordion - daverupert.com

At the risk of being a broken record; HTML really needs <accordion> , <tabs>, <dialog>, <dropdown>, and <tooltip> elements. Not more “low-level primitives” but good ol’ fashioned, difficult-to-get-consensus-on elements.

Hear, hear!

I wish browsers would prioritize accessibility improvements over things like main thread scheduling optimization to unblock tracking pixels and the Sisyphean task of competing with native.

If we really want to win, let’s make it easy for everyone to access the Web.

A Modern CSS Reset - Andy Bell

Some very smart ideas in here for resetting default browser styles, like only resetting lists that have classes applied to them:

ul[class],
ol[class] {
  padding: 0;
}

I select only lists that do have a class attribute because if a plain ol’ <ul> or <ol> gets used, I want it to look like a list. A lot of resets, including my previous ones, aggressively remove that.

Thinking vs Choosing – The Haystack

There seems to be a tendency to repurpose existing solutions to other people’s problems. I propose that this is the main cause of the design sameness that we encounter on the web (and in apps) today. In our (un)conscious attempts to reduce the effort needed to do our work, we’ve become experts in choosing rather than in thinking.

A very thoughtful piece from Stephen.

When we use existing solutions or patterns, we use a different kind of thinking. Our focus is on finding which pattern will work for us. Too quickly, we turn our attention away from closely examining the problem.

Initial thoughts on standardizing form controls | Greg Whitworth

Greg has done a lot of research into developer frustrations with customising form controls.

My current thinking in this space, and I know some folks will find this controversial, but I think we should completely standardize in-page form controls with no limitations on their styling capabilities. What do I mean by in-page controls? I am referring to any form control or component that is rendered within the content process. This standardization would include the sub-parts and their related states and how these are exposed (probably through CSS psuedo classes or HTML attributes). This will enable the shadow-dom to be encapsulated while providing web developers with a consistent experience to adjust to match their brand and needs of their site/application.

8 DOM features you didn’t know existed - LogRocket Blog

If you ignore the slightly insulting and condescending clickbaity title, this is a handy run-down of eight browser features with good support:

  1. extra arguments in addEventListener(),
  2. scrollTo(),
  3. extra arguments in setTimeout() and setInterval(),
  4. the defaultChecked property for checkboxes,
  5. normalize() and wholeText for strings of text,
  6. insertAdjacentElement() and insertAdjacentText(),
  7. event.detail, and
  8. scrollHeight and scrollWidth.

How to land on the Moon

Take a tour of the Lunar Module.

The LM (or “LEM”, as it’s pronounced) has the appearance of an aeronautical joke, with not a trace of streamlining. Instead, it’s an insect-like asymmetrical collection of legs, angles, bulges, and surfaces that’s very hard to visualize. Frankly, it looks like it was thrown together on a Friday afternoon by someone in a hurry to go fishing.

This page is a truly naked, brutalist html quine.

The Lost tags of HTML

I’ll be in my bunk.

Is CSS Turing Complete? | Lara Schenck

This starts as a good bit of computer science nerdery, that kind of answers the question in the title:

Alone, CSS is not Turing complete. CSS plus HTML plus user input is Turing complete!

And so the takeaway here is bigger than just speculation about Turing completeness:

Given that CSS is a domain-specific language for styling user interface, this makes a lot of sense! CSS + HTML + Human = Turing complete.

At the end of that day, as CSS developers that is the language we really write. CSS is incomplete without HTML, and a styled interface is incomplete without a human to use it.

Web Components will replace your frontend framework

I’ve often said that the goal of a good library should be to make itself redundant. jQuery is the poster child for that, and this article points to web components as the way to standardise what’s already happening in JavaScript frameworks:

Remember when document.querySelector first got wide browser support and started to end jQuery’s ubiquity? It finally gave us a way to do natively what jQuery had been providing for years: easy selection of DOM elements. I believe the same is about to happen to frontend frameworks like Angular and React.

The article goes on to give a good technical overview of custom elements, templates, and the Shadow DOM, but I was surprised to see it making reference to the is syntax for extending existing HTML elements—I’m pretty sure that that is, sadly, dead in the water.

HTML periodical table (built with CSS grid)

This is a nifty visualisation by Hui Jing. It’s really handy to have elements categorised like this:

  • Root elements
  • Scripting
  • Interactive elements
  • Document metadata
  • Edits
  • Tabular data
  • Grouping content
  • Embedded content
  • Forms
  • Sections
  • Text-level semantics

BEM: 4 Hang-Ups & How It Will Help Your CSS Organization

A few common gotchas when using BEM, and how to deal with them.

CSS Remedy

This is a really interesting approach that isn’t quite a CSS reset or a normalisation. Instead, it’s an experiment to reimagine what a default browser stylesheet would be like if it were created today, without concerns about backwards compatibility:

Applies basic styling to form elements and controls, getting you started with custom styling. We want to find the balance between providing a base for implementing a custom design, and allowing OS-level control over how form inputs work (like how a number pad works on iOS).

Provides a very lightweight starter file, with generic visual styling that you will want to replace. This isn’t as robust or opinionated as a starter-theme or framework. We’ve leaned toward specifying less, so you have less to override. (We haven’t defined any font families, for example.)

You can contribute by adding issues.

How do you figure? | CSS-Tricks

A good reminder from Chris—prompted by Scott O’Hara’s article—that the figcaption element and the alt attribute do different things. If you use an empty alt attribute on an img inside a figure, then your figcaption element is captioning nothing …and no, using the same text for both is not the solution.
