1/19 Eleven years after a church picnic in New York killed a thousand people, a company picnic in Chicago killed 844 more. The ship never left the wharf. She rolled over while the band was playing, in twenty feet of water, six metres from the bank. The SS Eastland. A 🧵. #maritimehistory

v0.0.191 of Modern Web Guidance is out and it's a big one! *16* new guides covering: web components by @castastrophe.bsky.social Cross-Origin Storage by @tomayac.com security by @rowan.fyi UI and PWA by @jamessw.com and @sturobson.com Wasm by @sbc100.bsky.social github.com/GoogleChrome...

accessible-web-components: Make custom elements accessible by default, setting roles and ARIA state via the ElementInternals ARIA mixin, managing focus with delegatesFocus, and keeping ARIA relationships within a single shadow root.
custom-elements: Define, register, and manage the lifecycle of autonomous custom elements, covering constructor rules, lifecycle callbacks, upgrade timing, attribute/property reflection, and naming conventions.
form-associated-custom-elements: Make a custom control participate natively in forms with formAssociated and ElementInternals, submitting its own value, integrating with constraint validation, and reacting to reset, disable, and state-restore.
prerendering-custom-elements: Server-render a custom element, then hydrate it in place without re-rendering or a flash of unstyled content.
shadow-dom: Encapsulate a component's DOM and styles with Shadow DOM, construct the tree efficiently with HTML templates, and project consumer content with slots.
styling-web-components: Style across the shadow boundary with :host selectors, inherited and custom properties for theming, ::slotted and ::part, and cascade layers and container queries inside components.
web-components: Orientation and cross-cutting principles for authoring and using Web Components, covering Custom Elements, Shadow DOM, templates and slots, Declarative Shadow DOM, styling across the shadow boundary, Form-Associated Custom Elements, and accessibility requirements. Use this guide when building reusable UI components, design systems, or server-rendered custom elements.
avoid-redundant-large-asset-downloads: Avoid re-downloading and re-storing large shared assets, such as AI models, Wasm modules, or fully-bundled JavaScript libraries, that a visitor's browser may already hold from an unrelated site.
load-shared-resources-declaratively: Serve popular, unmodified scripts, stylesheets, and JavaScript modules from a shared cross-origin cache using markup or import syntax alone, witho…

New Guides
migrate-web-app-origin: Transfer an installed web app to a new origin while preserving user configuration and OS-level shortcuts.
local-network-access: Access resources on a user's local network or loopback interface from a public web application.
trusted-types: Help prevent DOM-based XSS attacks by ensuring all untrusted content is sanitized before being inserted into the page.
responsive-table: Build a data table that presents tabular data with proper header semantics, and remains readable and navigable on small screens and with assistive technologies.
spatial-navigation: Implement accessible spatial navigation using arrow keys that works correctly in different layout modes (grid etc)
cpp-on-the-web: Compile C/C++ to WebAssembly using Emscripten

Updated the animated-select-picker guide to advise using standard value attributes on <option> elements to ensure standard form submission behavior.
Updated the branded-select-styling guide to emphasize retaining standard value attributes on <option> elements to preserve default form submission behaviors.
Updated the custom-select-picker-layouts guide with guidance on using :open::picker(select) selectors, customizing the ::checkmark pseudo-element, wrapping <selectedcontent> in a <button>, and managing keyboard navigation and accessibility constraints for grid layouts.
Updated the rich-media-picker guide to clarify that standard value attributes should be maintained on <option> elements to preserve form submission functionality.
Updated the out-of-order-html-streaming guide to document the full suite of static and streaming DOM insertion methods, detailing built-in sanitizer behaviors, WritableStream integration, and processing instruction marker practices.
Updated the sanitize-untrusted-html guide to detail node manipulation patterns using Document.parseHTML() to avoid mutation XSS, explain child preservation rules via replaceWithChildrenElements, and provide aligned DOMPurify fallback configurations.

Removed the prevent-text-wrapping guide.

HTML processing instructions: Added Chrome 150 and Edge 150 support in out-of-order-html-streaming.

A four-column table titled "Benchmark Evaluations" comparing unguided versus guided pass rates across 132 tasks and 1,124 assertions.

Row 2: claude_code (claude-sonnet-5) achieved a 54% unguided pass rate and an 87% guided pass rate, an uplift of +33 percentage points.

Row 3: antigravity (gemini-3.8-flash-medium) achieved a 65% unguided pass rate and a 91% guided pass rate, an uplift of +26 percentage points.

Don't miss Simon's experiment with asking Claude's new free tier to draw a WebGL version of "Pelican on a bike": -> static.simonwillison.net/static/2026/... "Solid effort" is an understatement IMHO, especially for "free" (this may eat a considerable amount of "free" 5h allowance).

The most interesting thing about Sonnet 5.5 is that it's now the model used for the free tier on claude.ai. OpenAI's ChatGPT free tier uses Luna 5.6, which means Anthropic currently have a much more capable free offering.

I ran this prompt against that free tier:

build me an HTML page that renders a three-dimensional pelican riding a bicycle using WebGL

And got back this page, which is a solid effort.
