Use when applies to CSS and JavaScript implementations of modals, overlays, pop-ups, cookie banners, newsletter sign-up dialogs, and promotional overlays.

Consider both SEO impact (Google) and accessibility (WCAG focus management).
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.

# Avoid intrusive interstitials Intrusive interstitials are a barrier for screen reader users who may not know a modal is blocking the page — they hear content that appears interactive but cannot activate it. Keyboard users may find focus trapped behind an overlay with no way to dismiss it. Users on mobile are most affected visually, as full-screen pop-ups eliminate all access to content until dismissed. Additionally, Google Search penalizes mobile pages with intrusive interstitials in search rankings. ## Quick Reference - Full-screen pop-ups that cover the main content immediately on mobile page load are penalized by Google Search (January 2017 Intrusive Interstitials Update) - Acceptable interstitials: age verification, legally required notices (cookie consent where legally mandated), login walls for private content - Unacceptable: pop-ups covering the main content area on mobile that are not easy to dismiss - For accessibility: modal dialogs must trap focus, be dismissible by keyboard (Escape key), and return focus to the trigger element - WCAG 2.1 SC 2.1.2 (No Keyboard Trap): users must be able to move focus away from any component using the keyboard ## Check …

How to install
mdr add thedaviddias/front-end-checklist/interstitials@sha256:2689f3e03963e034The 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.
