How to fix focus not visible on BigCommerce

Steps for BigCommerce

1. In your BigCommerce Admin, go to Storefront → My Themes → click Customize on the active theme → click Advanced → Edit Theme Files.
2. Open assets/scss/components/base/_base.scss (Cornerstone theme) or the equivalent main CSS/SCSS file. Search for 'outline'.
3. Delete or override any `outline: none` rules, then add the focus styles below.
4. If you are not on the Stencil framework, go to Storefront → Script Manager and inject a small `<style>` tag with the focus CSS, or add it to the custom footer script.
5. Save and preview the theme, then tab through the storefront to verify.

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.
