Observation Details
Focusing product card by keyboard navigation does not add visible focus state.
Remediation Notes
A focus state must be defined for all interactive, focusable elements. Ideally, a visual distinct focus state uses an outline or other larger area changes to the product card.
If using color change for focus state, ensure to meet minimum color contrast between different states (1.4.3 Contrast (Minimum)) and to not only rely on color change (1.4.1 Use of Color).
