Shopify Development w/ WCAG Accessibility Requirements

Existing high-traffic Shopify-based ecommerce seller needs to update their template/theme structure to meet WCAG 2.1 AA-level accessibility requirements.

This project includes adjustments to primary pages like PLP and PDP, as well as adjustment to their megamenu configuration to achieve complete keyboard navigation capability.

I'm estimating 5-10 working hours as the development changes are likely to lean toward basic structural/hierarchy adjustment, with no conditional logic or special features.

This is currently a one-time project, but I anticipate many others like it in the near future. Please include any experience with WCAG in your proposal notes.

Thank you!
