Postscript on Shopify — accessibility integration audit
Accessibility hot-spots in Postscript
Postscript popup iframe focus management
Partial auto-fixWCAG: 2.1.2 No Keyboard Trap
Apps that inject their UI in an iframe (popup overlays, embedded review widgets) must trap keyboard focus inside the iframe while open and return focus to the trigger on close. Iframes that capture focus indefinitely fail WCAG 2.1.2; iframes that never capture focus on open fail to meet user expectations.
Postscript phone capture form-label associations
Auto-fixWCAG: 3.3.2 Labels or Instructions
Apps that inject form fields (email capture, SMS opt-in, custom checkout fields) often ship with placeholder-only labels. Auto-fix rewrites the field markup to include a programmatic <label for> + matching id + correct autocomplete value.
TCPA disclaimer contrast
Auto-fixWCAG: 1.4.3 Contrast (Minimum)
The TCPA-required consent disclaimer renders in muted gray to deemphasize. This styling typically falls below 4.5:1 against the popup background. Auto-fix raises the disclaimer to a contrast-compliant gray that still reads as deemphasized.
Postscript opt-in confirmation async status announcements
Auto-fixWCAG: 4.1.3 Status Messages
Apps that update content asynchronously — "Discount applied", "Subscription saved", "Review submitted" — frequently announce visually only without a role="status" or aria-live region for screen readers. Auto-fix wraps the toast / status container in role="status" so screen readers announce the update.
FAQ
Is Postscript accessible by default on Shopify?
Postscript's vendor-default templates pass standard accessibility checks; merchant customization and the structural patterns the app injects are where regressions appear. The hot-spots above are the predictable failure modes when a real Shopify storefront is audited end to end with Postscript installed.
Does AccessComply fix Postscript accessibility issues automatically?
Yes — for the categories marked auto-fix above. AccessComply scans the live storefront with Postscript active, identifies the WCAG failures the app surface contributes, and writes source-code fixes to your theme via the Shopify Admin API. Fixes that touch the Postscript layer directly are flagged for Postscript support follow-up.
Should I uninstall Postscript for accessibility reasons?
No. Postscript is a widely-used Shopify app and the accessibility issues are addressable without removing the app. The hot-spots above are predictable structural patterns — every app that does what Postscript does has a similar list. The fix is to remediate at the storefront level, not to swap apps.
Will fixing Postscript accessibility break my brand customizations?
No. AccessComply's fixes are scoped to specific WCAG-relevant attributes (aria-label, role, autocomplete, focus styles, contrast on text) and do not change merchant copy, layout, or branding. If a fix produces a regression, the post-fix re-scan triggers automatic rollback to the pre-fix state.
Do I need Postscript-specific permissions for AccessComply to scan?
No additional permissions. AccessComply scans the rendered storefront the same way Googlebot or any visitor does — through Playwright + axe-core. The scan reads the same HTML the customer sees, including everything Postscript injects at runtime.
Scan your store with Postscript installed
AccessComply scans the live storefront — the same HTML Postscript renders for your customers — and writes source-code fixes for the hot-spots above.
