Why learn Accessibility ?

Web accessibility is still too often overlooked… even though it directly concerns a significant portion of users.

Today, nearly 15% of the world's population lives with a disability. Without accessibility, your applications simply become unusable for millions of people.

But the issue doesn't stop there.

An accessible site is also a better designed site: clearer, more structured, more performant. By applying best practices such as semantic HTML, proper contrast, or consistent navigation, you improve the experience for all users.

Accessibility is also a legal matter. Standards like WCAG and RGAA are already mandatory in many contexts, and their adoption is only increasing.

Finally, there's a direct impact on SEO. Search engines favor sites that are well-structured, fast, and understandable, which directly aligns with accessibility principles.

For a developer, mastering these concepts shows that you're capable of building professional, inclusive applications that comply with modern standards.

And that's a skill that's rare… and highly valued.

By the end of this course

You will be able to design accessible, compliant, and inclusive interfaces like a professional developer.
