How to fix scrollable region focusable on WooCommerce

Steps for WooCommerce

1. In your WordPress Admin, go to Appearance → Theme File Editor (or use a child theme) and locate the template that outputs the scrollable region — commonly woocommerce/single-product/description.php or a custom template part.
2. Find the wrapping element (div, section, etc.) that carries the overflow-scroll CSS class.
3. Add tabindex="0" and aria-label="Product description" to that element's opening tag.
4. Add a :focus outline rule to your child theme's style.css: .woocommerce-product-details__short-description:focus { outline: 2px solid #005fcc; }
5. Alternatively, install the 'WP Accessibility' plugin (by Joe Dolson), which provides helpers for common WCAG fixes, though tabindex may still need to be added manually to custom containers.
6. Save and verify with keyboard Tab navigation on the front end.

<div class="product-description"
     tabindex="0"
     aria-label="Product description"
     style="max-height:200px; overflow-y:auto;">
  <!-- scrollable content here -->
</div>

What is scrollable region focusable?

A "scrollable region" is any box on your page that has a scrollbar — for example, a product description box with a fixed height, a reviews section with overflow scrolling, a custom dropdown list, or a side-by-side comparison table. When a sighted user without a mouse (or a user who relies entirely on the keyboard) presses Tab to navigate, they must be able to reach that box and scroll through its content using arrow keys. If the scrollable container has no focusable element inside it and no tabindex attribute, the keyboard simply skips it entirely, making the content inside inaccessible. WCAG Success Criterion 2.1.1 ("Keyboard") requires that all functionality — including scrolling — be operable by keyboard alone.

Keyboard accessibility is a legal requirement in many jurisdictions (ADA in the US, EN 301 549 in the EU, AODA in Canada) — failing it exposes your business to accessibility complaints and litigation. Shoppers who rely on keyboards (people with motor disabilities, power users, switch-access device users) cannot read the content hidden inside your scrollable box, which directly kills conversions for that segment. Search engines also value accessible, well-structured pages as a quality signal. Fixing this is usually a one-line code change and removes a real barrier for real customers.
