How to fix focus not visible on WooCommerce

Steps for WooCommerce

1. In WordPress Admin, go to Appearance → Themes → click your active theme → Edit (or use Appearance → Theme File Editor).
2. Open style.css (or the child theme's style.css). Search for 'outline: none' or 'outline: 0'.
3. Remove or override those rules, then add the universal focus rule from the code snippet below.
4. Alternatively, install the Simple Custom CSS plugin and paste the rule there so it survives theme updates.
5. Save changes and test by tabbing through the shop, product, cart, and checkout pages.

What is focus not visible?

When someone navigates your store using only a keyboard (Tab, Shift+Tab, arrow keys), their browser highlights the currently focused element — a button, link, form field, etc. — so they know where they are. This is called the "focus indicator" or "focus ring." The problem occurs when a theme or custom CSS removes or hides this highlight (often via `outline: none` or `outline: 0`), making the page look cleaner but leaving keyboard users completely lost. WCAG Success Criterion 2.4.7 (Focus Visible) requires that this focus indicator always be visible.

Roughly 7% of internet users navigate primarily by keyboard — including people with motor disabilities, power users, and anyone whose mouse has stopped working. If they can't see where focus is, they literally cannot use your store: they can't tell which product they're about to add to the cart, which field they're typing in, or which button they're about to press. Beyond lost sales, hiding focus indicators is a WCAG 2.1 Level AA violation, which creates legal exposure under the ADA, the European Accessibility Act, and similar laws in many countries. Accessible stores also tend to rank better because Google uses accessibility signals as a quality indicator.
