Use when reviewing sticky navigation, consent banners, chat widgets, skip links, or any fixed-position UI. Validate the actual tab order and viewport behavior at realistic zoom levels.
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
# Keep focused elements unobscured A visible focus ring is not enough if the focused element sits behind a sticky header or footer. Keyboard users need to see the actual focused control and the focus indicator at the same time in order to continue the task. ## Quick Reference - Sticky UI must not cover the focused control while keyboard users tab through the page - Use `scroll-padding` or equivalent spacing when fixed headers or footers are present - Test with cookie banners, chat widgets, and consent bars open - Re-test at zoomed and mobile layouts where overlap problems usually appear ## Check Audit keyboard focus with all sticky UI active. Check headers, footers, cookie banners, promo bars, and chat launchers for cases where the focused element scrolls underneath them. ## Fix Add layout spacing such as scroll-padding, reduce overlay height, or change focus/scroll behavior so the focused element remains visible when tabbing. ## Explain Explain WCAG Focus Not Obscured, why fixed-position UI commonly breaks it, and how scroll-padding and overlay layout choices prevent the issue. ## Code Review …

How to install
mdr add thedaviddias/front-end-checklist/focus-not-obscured@sha256:4574e554850c17d8The line at the top of this page pins the label git:20261004.4b0ddb9, 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.
