Use when a fused-render view looks or behaves wrong in one desktop browser only (Chrome/Edge, Firefox, Safari/WebKit), or to check support for a CSS/JS feature before using it — deep reference behind the authoring skill's mandatory Cross-browser section.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cross-browser views (desktop)
A view is opened in whatever the user's **default desktop browser** is — Chrome/Edge, Firefox, Safari — and inside **WKWebView** (the macOS pinned popover, SPEC §25). **WebKit rules apply even when the author's browser is Chrome.** Written against Chrome alone = shipped for one engine.
Scope is **computers only**: phones and tablets are out. Nothing here is about touch, viewport zoom, mobile toolbars or iOS/Android.
## Support target
- Use only features MDN marks **Baseline: Widely available**. Not in this file → check the MDN compat table. Never assume from Chrome.
- **Newly available** (last ~30 months) → `@supports (…) {}` with a fallback that still works, or drop it.
- Chrome-only → don't. There is no "just for now".
- No transpiler, no autoprefixer, no build step (authoring contract). Prefixes are hand-written where the table says so.
## Paste-in baseline
Drop into every view's `<style>`, beneath the theme tokens (`fused-render-theming`):
```css
*, *::before, *::after { box-sizing: border-box; }
body { margin: 0; }
button, input, select, textarea { font: inherit; color: inherit; margin: 0; }

How to install
mdr add fusedio/fused-render/fused-render-cross-browser@sha256:3973ea1d5926e53bThe line at the top of this page pins the label git:20261019.6575054, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
