Why this program matters

Without mastering the ARIA role='dialog', your modals and dialogs become invisible to screen readers, excluding 15% of the population with disabilities.
68% of sites tested by WebAIM show critical accessibility errors on pop-ups, causing systematic failures on RGAA audits and project delays of 3 to 6 months.
Non-compliance exposes your company to DGCCRF fines of up to 300 000 € per notice, along with reputation loss that can cut 20% of annual revenue.
Every month without correct implementation multiplies the risks of user complaints and class actions, directly jeopardizing your career and the company's digital competitiveness.
