Accessibility

These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.

ARIA

Using ARIA attributes in roles where they are prohibited can mean that important information is not communicated to users of assistive technologies. Learn more about prohibited ARIA roles.

Why this matters

Performance issues directly impact user engagement and conversion rates.

Failing Elements
Elemento previo div.clo-hero-carousel__inner > div.clm-generic-carousel > div.clm-generic-carousel__carousel > div.clm-generic-carousel__nav
Siguiente elemento div.clo-hero-carousel__inner > div.clm-generic-carousel > div.clm-generic-carousel__carousel > div.clm-generic-carousel__nav

These are opportunities to improve the usage of ARIA in your application which may enhance the experience for users of assistive technology, like a screen reader.

Names and labels

When a button doesn't have an accessible name, screen readers announce it as "button", making it unusable for users who rely on screen readers. Learn how to make buttons more accessible.
