Page Embedded Permission Control (` permission ` element)

194028 – Add limits to the amount of JavaScript that can be loaded by a website

Now this is a feature request I can get behind!

A user must provide permission to enable geolocation, or notifications, or camera access, so why not also require permission for megabytes of JavaScript that will block the main thread?

Without limits, there is no incentive for a JavaScript developer to keep their codebase small and dependencies minimal. It’s easy to add another framework, and that framework adds another framework, and the next thing you know you’re loading tens of megabytes of data just to display a couple hundred kilobytes of content.

I’m serious about this. It’s is an excellent proposal for WebKit, similar to the never-slow mode proposed by Alex for Chromium.

This is a really interesting proposal, and I have thoughts.

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?

Notes on `lang` by Taylor Hunt on CodePen

A really deep dive into the lang attribute, and the :lang() pseudo-class (hitherto unknown to me). This is all proving really useful for a little side project I’m working on.

A nice explanation of the ruby element in HTML5: very handy for marking up phonetic pronunciation.
