WHATWG HTML Standard VS csswg-drafts

WHAT-WG HTML

There's a long-standing WHATWG feature request open for it here: https://github.com/whatwg/html/issues/2791

And several userland custom element implementation, like https://www.npmjs.com/package//html-include-element

One of the cool things that you can do with client-side includes and shadow DOM is render the included HTML into a shadow root that has s, so that the child content of the include element is slotted into a shell implemented by the included HTML.

This lets you do things like have the main page be the pre-page content and the included HTML be a heavily cached site-wide shell, and then another per-user include with personalized HTML - all cached appropriately.

The `allow` attribute on iframes is a relatively recent API addition from 2017

https://github.com/whatwg/html/pull/3287

I think there's a pretty strong argument at this point for this kind of replacing DOM with a response behavior being part of the platform.

I think the first step would be an element that lets you load external content into the page declaratively. There's a spec issue open for this: https://github.com/whatwg/html/issues/2791

And my custom element implementation of the idea: https://www.npmjs.com/package/html-include-element

Then HTML could support these elements being targets of links.

I thought, oh, that's not so bad. Then I realized what I was looking at was a 10 page index.

I'd love to see something like HTMX get standardized, but I'm extremely pessimistic for HTMX's prospects for standardization in HTML.

In talking to a few standards folks about it, they've all said, "oh, yeah, you want declarative AJAX; people have tried and failed to get that standardized for years." Even just trying to get

to target a section of the page that isn't an has been argued about and hashed out for years.<p>Why is that? Well, for example, here's the form you have to fill out to start standardizing a front-end feature. <a href="https://github.com/whatwg/html/issues/new?assignees=&labels=addition%2Fproposal%2Cneeds+implementer+interest&projects=&template=1-new-feature.yml">https://github.com/whatwg/html/issues/new?assignees=&labels=...</a><p>It asks three main questions:<p>* What problem are you trying to solve?

The issue with a single global event handler is discussed here: https://github.com/WICG/close-watcher#a-single-event

If you use popover="", you get the kind of functionality you're discussing for free. For

, the discussion is in progress and reaching a conclusion: https://github.com/whatwg/html/issues/9373

The tracking issue: https://github.com/w3c/csswg-drafts/issues/8659

As noted there, okHSL/HSV keeps the perceptual uniformity by removing some peaks beyond the geometric limit of HSL/HSV, and it is unclear whether it is what users do expect or not.

The idea is that you should be able to set accent color via accent-color CSS property. It is discussed that there should be access to the color value of this property, e.g. via AccentColor or AccentColorText.

What do you mean by "official documentation"? The specification [1]? MDN [2]?

[2] https://developer.mozilla.org/en-US/docs/Web/CSS

The former is not meant as a learning resource for new web devs and the latter usually has information about the "baseline" support ond browser compatibility tables.

> RESOLVED: Start ED of css-mixins for CSS Custom Functions and Mixins

Recently I was reading the Learn CSS the pedantic way book and the definition for inline boxes did not match the way that anonymous block boxes were generated when an inline-level element had a block-level element as its child. So I went looking elsewhere for a more appropriate definition for that case and found this issue on standards: https://github.com/w3c/csswg-drafts/issues/1477 It was really interesting to know that I was not the only one confused. My question was: Does the inline-box generated by the inline-level element contains the box generated by the block-level child or there wasn't an inline-box that was a parent of them all but there were 2 siblings inline-level boxes of the block-level box that were wrapped in another anonymous block boxes? Reading that issue I got to know the concept of fragments, which I did not know browsers had. But the issue seems to suggest that the box tree for this case should have the inline-box as being a parent of the block-box. Which led me to another question, in that case, if I apply a border to the parent inline-level element, shouldn't it apply to the overall box that is generated (it does not)? The answer is that borders between block-boxes and inline-level boxes should not intersect but that is really difficult to derive from reading the standards alone. Anyway it was headache-inducing trying to learn the box-model pedantically :)

With all the recent CSS improvements I still miss the possibility to have working transition to "height:auto". The issue [1] on csswg-drafts is the most upvoted one. At least we can now use css grid and track sizes transitions, but it's far from intuitive, transition for "height:auto" should just work.

Masonry isn’t ready to be shipped as there are still quite a few open spec issues [^1] that need to be resolved first.

i had the same reaction, it seems like a very weird syntax. but after reading the discussion i get it: you're telling a form field to behave like a normal html element, instead of behaving like a form field.

I'm talking about on the web.

Apple proposed the standard: https://github.com/w3c/csswg-drafts/issues/3299

Safari 12.1 was the first browser to ship with color-scheme and prefers-color-scheme support: https://developer.mozilla.org/en-US/docs/Web/CSS/@media/pref... https://developer.mozilla.org/en-US/docs/Web/HTML/Element/me...
