Web Form Conundrum: disabled or readonly? | Aaron Gustafson

Good question! And a good answer:

If you really need it, which you probably don’t, readonly is what you want.

Web Components: The Long Game – Infrequently Noted

One of the things we’d hoped to enable via Web Components was a return to ctrl-r web development. At some level of complexity and scale we all need tools to help cope with code size, application structure, and more. But the tender, loving maintainance of babel and webpack and NPM configurations that represents a huge part of “front end development” today seems…punitive. None of this should be necessary when developing one (or a few) components and composing things shouldn’t be this hard. The sophistication of the tools needs to get back to being proportional with the complexity of the problem at hand.

I completely agree with Alex here. But that’s also why I was surprised and disheartened when I linked to Monica’s excellent introduction to web components that a package manager seemed to be a minimum requirement.

Occasionally, people e-mail me to say something along the lines of “I’ve come up with something to replace HTML!”.

Five years ago, Hixie outlined the five metrics that a competitor to the web would have to score well in:

  1. Be completely devoid of any licensing requirements.
  2. Be vendor-neutral.
  3. Be device-neutral and media-neutral.
  4. Be content-neutral.
  5. Be radically better than the existing Web.

You come at the king, you best not miss.

Mapping in HTML – a proposal for a new element – Terence Eden’s Blog

I quite like this proposal for geo element in HTML, especially that it has a fallback built in (like video). I’m guessing the next step is to file an issue and create a web component to demonstrate how this could work.

That brings up another question: what do you name a custom element that you’d like to eventually become part of the spec? You can’t simply name it geo because you have to include a hyphen. geo-polyfill? geo-proposal? or polyfill-geo? proposal-geo?

Tooltips & Toggletips

Another great deep dive by Heydon into a single interface pattern. This time it’s the tooltip, and its cousin, the toggletip.

There’s some great accessibility advice in here.

Jekyll Includes are Cool - daverupert.com

Dave explains how Jekyll Includes are starting to convert him to web components. The encapsulation is nice and neat. And he answers the inevitable “but why not use React?” question:

Writing HTML that contains JavaScript, not JavaScript that contains HTML, feels good to me.

The key feature for me is that this approach doesn’t have to depend on JavaScript in the browser:

I like that Web Components are an entirely client-side technology but can be rendered server-side in existing tech stacks whether it’s Jekyll, Rails, or even some Enterprise Java system.

Let small include subheadings? · Issue #929 · w3c/html

Here’s an interesting proposal to slightly amend the semantics of the small element so it could apply to the use-case that hgroup was trying to cover.

Fixing fieldsets — That Emil is Emil Björklund

This is an excellent proposal from Emil. If we can apply display: contents to fieldsets, then we would finally have a way of undoing the byzantine browser styles that have hindered adoption of this element. This proposal also ensures backwards compatibility so there’d be no breakage of older sites:

The legacy appearance of fieldsets probably needs to be preserved for compatibility reasons. But display: contents is not supported in any old browsers, and is most likely used on exactly zero sites using the legacy look of fieldsets.

Whaddya say, browser makers?

Inclusively Hidden | scottohara.me

Comparing different ways to hide content accessibly:

There are three reasons behind hiding content in an interface, and it’s important to identify what those reasons are, as they will correlate with the appropriate technique needed to hide such content.

  1. Temporarily Hidden Content
  2. Purposefully Visually Hidden Content
  3. Purposefully Visual-Only Content

A Todo List

A great step-by-step walkthrough by Heydon of making an accessible to-do list, the “Hello World” of JavaScript frameworks.

There’s a lot of great knowledge in here that can be applied to plenty of other interface elements too.

State of Responsive Images 2017 - Cloud Four

Jason revisits responsive images. On the whole, things are looking good when it comes to browser support, but he points out that scrset’s precursor in CSS—image-set seems to have dropped off the radar of most browser makers, which is a real shame.

Do we need a new heading element? We don’t know - JakeArchibald.com

Jake is absolutely spot-on here. There’s been a lot of excited talk about adding an h element to HTML but it all seems to miss the question of why the currently-specced outline algorithm hasn’t been implemented.

This is a common mistake in standards discussion — a mistake I’ve made many times before. You cannot compare the current state of things, beholden to reality, with a utopian implementation of some currently non-existent thing.

If you’re proposing something almost identical to something that failed, you better know why your proposal will succeed where the other didn’t.

Jake rightly points out that the first step isn’t to propose a whole new element; it’s to ask “Why haven’t browsers implemented the outline for sectioned headings?”

(I added a small historical note in the comments pointing to the first occurrence of this proposal way back in 1991.)

Teaching in Porto, day one

Today was the first day of the week long “masterclass” I’m leading here at The New Digital School in Porto.

When I was putting together my stab-in-the-dark attempt to provide an outline for the week, I labelled day one as “How the web works” and gave this synopsis:

The internet and the web; how browsers work; a history of visual design on the web; the evolution of HTML and CSS.

There ended up being less about the history of visual design and CSS (we’ll cover that tomorrow) and more about the infrastructure that the web sits upon. Before diving into the way the web works, I thought it would be good to talk about how the internet works, which led me back to the history of communication networks in general. So the day started from cave drawings and smoke signals, leading to trade networks, then the postal system, before getting to the telegraph, and then telephone networks, the ARPANET, and eventually the internet. By lunch time we had just arrived at the birth of the World Wide Web at CERN.

It wasn’t all talk though. To demonstrate a hub-and-spoke network architecture I had everyone write down someone else’s name on a post-it note, then stand in a circle around me, and pass me (the hub) those messages to relay to their intended receiver. Later we repeated this exercise but with a packet-switching model: everyone could pass a note to their left or to their right. The hub-and-spoke system took almost a minute to relay all six messages; the packet-switching version took less than 10 seconds.

Over the course of the day, three different laws came up that were relevant to the history of the internet and the web:

Metcalfe’s Law
The value of a network is proportional to the square of the number of users.
Postel’s Law
Be conservative in what you send, be liberal in what you accept.
Sturgeon’s Law
Ninety percent of everything is crap.

There were also references to the giants of hypertext: Ted Nelson, Vannevar Bush, and Douglas Engelbart—for a while, I had the mother of all demos playing silently in the background.

After a most-excellent lunch in a nearby local restaurant (where I can highly recommend the tripe), we started on the building blocks of the web: HTTP, URLs, and HTML. I pulled up the first ever web page so that we could examine its markup and dive into the wonder of the A element. That led us to the first version of HTML which gave us enough vocabulary to start marking up documents: p, h1-h6, ol, ul, li, and a few others. We went around the room looking at posters and other documents pinned to the wall, and starting marking them up by slapping on post-it notes with opening and closing tags on them.

At this point we had covered the anatomy of an HTML element (opening tags, closing tags, attribute names and attribute values) as well as some of the history of HTML’s expanding vocabulary, including elements added in HTML5 like section, article, and nav. But so far everything was to do with marking up static content in a document. Stepping back a bit, we returned to HTTP, and talked about difference between GET and POST requests. That led in to ways of sending data to a server, which led to form fields and the many types of inputs at our disposal: text, password, radio, checkbox, email, url, tel, datetime, color, range, and more.

With that, the day drew to a close. I feel pretty good about what we covered. There was a lot of groundwork, and plenty of history, but also plenty of practical information about how browsers interpret HTML.

With the structural building blocks of the web in place, tomorrow is going to focus more on the design side of things.
