Magento 2 et l'accessibilité web : rendre votre boutique conforme aux normes ADA
Why Web Accessibility Matters for Your Magento 2 Store
Web accessibility isn't just a nice-to-have fonctionnalité anymore - it's a legal prérequis and a smart entreprise move. The Americans with Disabilities Act (ADA) requires websites to be accessible to all utilisateurs, including those with disabilities.

Beyond compliance, accessible websites often rank better in moteur de recherches and reach a wider audience. Did you know that about 15% of the world's population experiences some form of disability? That's a significant market you don't want to exclude!

- Perceivable: Content doit être presentable in ways utilisateurs can perceive (text alternatives for images, captions for videos, etc.)
- Operable: Interface composants doit être operable (cléboard navigation, enough time to read contenu, etc.)
- Understandable: Information doit être understandable (clear language, predictable navigation, etc.)
- Robust: Content doit être robust enough to work with current and future utilisateur tools

}
// Ensure all interactive elements are focusable
[tabindex="-1"]:focus {
outline: none;
}
// Add skip navigation link (add to your header template)
<a href="#main-content" class="skip-link">Skip to main content</a>
// Then in your CSS
.skip-link {
position: absolute;
left: -9999px;
top: 0;
background: #0066cc;

z-index: 9999;
}
.skip-link:focus {
left: 0;
}

<button aria-label="Search">

<input type="text" id="search" aria-label="Search products" placeholder="Search products...">
// For product images
<img src="product.jpg" alt="Blue cotton t-shirt with company logo">
Color Contrast and Visual Accessibility

color: #ffffff;
}

</div>
