Web accessibility: why it is essential and how to integrate it?

Web accessibility, far from being a mere "bonus," is now a marker of quality, ethics, and performance. At Argonauts Agency, we believe that every digital project should address all users —not just a majority.
1️⃣ What do we mean by web accessibility?
Web accessibility means that "any user, regardless of their physical, sensory, mental or technical abilities, can view and interact with a website".
It concerns, in particular:
- Navigation is possible without a mouse (keyboard, voice command).
- A semantic structure for the content so that screen readers can understand it
- Sufficiently contrasting texts, textual alternatives to images
2️⃣ Why is accessibility essential?
🔹 Inclusion and right of access
The web is an integral part of our lives: employment, shopping, culture, public services. Making a website accessible means respecting a **universal right**.
🔹 Brand image and perceived quality
An accessible website conveys an image of seriousness, respect, and commitment.
🔹 SEO performance and expanded reach
Well-structured content, compatible with assistive technologies, is better referenced: it reaches a wider audience and improves the user experience.
3️⃣ Key principles for making your site accessible
1) Clear semantic structure
Use H1 to H4 tags, lists, tables "friendly to screen readers".
2) Textual alternatives
Each image must have an alt attribute describing the visual for visually impaired users.
3) Color contrast and readability
Ensure strong contrast between text and background. Text must be legible even for users with low vision.
4) Keyboard navigation and mobile compatibility
Make sure your site is usable with a keyboard, not just a mouse. Ensure that the mobile display remains smooth.
5) Accessible media
Add subtitles to videos, transcribe multimedia content, and choose automatic pause.
6) Regular inspection and maintenance
Accessibility is not a "one-off" state. It requires regular auditing, correction, and monitoring.
4️⃣ How to integrate accessibility into a web project
- Initial audit : identify existing access barriers.
- Definition of conformance level (e.g., WCAG AA)
- Design and development taking accessibility into account from the graphic charter, mock-ups, and code.
- User testing (people with disabilities, screen readers)
- Launch and monitoring : regular reports, content updates, internal training.
