The root cause was two-fold: + +1. **Wrong format** — `favicon` was set to `img/logo.svg`. Many browsers (older Chrome, + all versions of Safari on iOS/macOS, Windows taskbar/pinned-sites, and every version + of IE/Edge Legacy) do not support SVG as a favicon source. They silently ignore the + tag and display a generic blank icon. + +2. **Missing fallback files** — No `.ico` or `.png` favicon files existed in the repo, + so browsers that support only those formats had nothing to fall back to. + +| Criterion | Delivered | +|---|---| +| Favicon appears in browser tab | ✅ `favicon.ico` (16 + 32 + 48 px) served via `` | +| Works on all pages | ✅ `headTags` injects into every page's `` globally | +| Appears in bookmarks / home screen | ✅ `apple-touch-icon.png` (180×180) for iOS/macOS; `.ico` for Windows | +| No console errors | ✅ All referenced files exist; no 404s | + +--- + +## Root Cause + +``` +// Before — SVG-only favicon; ignored by Safari, Windows, older Chrome +favicon: 'img/logo.svg', +``` + +Browsers select a favicon using `` tags in the document ``. +Docusaurus only injects one tag from the `favicon` config key.

Picks `image/svg+xml` if it supports SVG icons (Chrome 80+, Firefox 41+). +2. Falls back to `image/png` sized `32x32` or `16x16` for everything else. +3.
