How to fix nested interactive on WooCommerce

Steps for WooCommerce

1. In your WordPress admin, go to Appearance → Theme Editor (or use a code editor / FTP client) and locate the theme template responsible for the affected component — commonly woocommerce/content-product.php, woocommerce/loop/add-to-cart.php, or a custom block/widget.
2. If your theme uses a block editor (FSE), go to Appearance → Editor, navigate to the template containing the issue, and inspect the block markup in Code Editor view (three-dot menu → Code editor).
3. Search for `<a` or `<button` tags that wrap another `<a>` or `<button>`. Refactor so only one interactive element wraps the action.
4. If the nesting comes from a WooCommerce core template override, copy the template to your child theme under /woocommerce/ and edit it there so updates don't overwrite your fix.
5. Install the axe DevTools browser extension and re-scan the fixed page to confirm the violation is gone.

What is nested interactive?

WCAG Success Criterion 4.1.2 requires that every user interface component has a name, role, and value that assistive technologies (like screen readers) can reliably understand. A "nested interactive" violation occurs when one interactive element — such as a `<button>`, `<a>`, `<select>`, or `<input>` — is placed inside another interactive element in the HTML. For example, putting a `<button>` inside an `<a>` tag, or an `<a>` link inside a `<button>`. HTML forbids this nesting, browsers handle it inconsistently, and screen readers and keyboard navigation can behave unpredictably. Adding `tabindex="-1"` or `aria-hidden="true"` to the inner element does NOT reliably hide it from assistive technology — screen readers can still discover and announce it, creating a confusing or broken experience.

Keyboard-only users and screen-reader users (a significant and legally protected segment of shoppers) can get stuck, confused, or blocked from completing a purchase when interactive controls are nested. In many jurisdictions — including the US (ADA), EU (EN 301 549), and UK (Equality Act) — inaccessible ecommerce stores face real legal exposure including complaints, audits, and lawsuits. Beyond legal risk, a broken checkout button or unclickable product link directly costs you conversions and revenue. Google also uses accessibility signals as a quality indicator, so fixing these issues can modestly improve crawlability and organic rankings over time.
