Declared vs rendered fonts
Most font checkers only read CSS. This tool reports both what stylesheets request and what the browser actually renders after fonts load. When a webfont fails or a fallback wins, the declared-vs-rendered table shows the difference.
| Signal | Declared CSS | Rendered browser pass |
|---|---|---|
| Source | HTML, linked CSS, @font-face | document.fonts + computed styles |
| Best for | Inventory, file URLs, Google/Adobe links | SPAs, CSS-in-JS, fallback detection |
