Web accessibility

What web accessibility is

Web accessibility is the practice of making websites and applications usable by everyone, including people with visual, hearing, motor or cognitive disabilities. That means a blind person using a screen reader can navigate the site, someone who cannot use a mouse can operate it by keyboard, text has enough contrast to be read, videos have captions, and content is structured clearly enough to understand. Accessibility removes barriers so that a disability does not prevent someone from using the web.

The guidelines: WCAG and RGAA

Accessibility is defined by recognised standards. The international reference is the WCAG (Web Content Accessibility Guidelines), organised around four principles summarised as POUR: content must be Perceivable, Operable, Understandable and Robust. In France, the RGAA (Référentiel Général d'Amélioration de l'Accessibilité) adapts WCAG into a legal framework, and accessibility is a legal obligation for public bodies and many large companies. Conformance is usually expressed in levels, with AA being the common target.

What it covers in practice

Accessible design touches many concrete details: sufficient colour contrast, text alternatives for images, captions and transcripts for media, full keyboard navigation, clear and consistent structure using proper headings and landmarks, labels on form fields, visible focus indicators, and content that does not rely on colour alone to convey meaning. Much of this comes from clean, semantic HTML and thoughtful design, rather than expensive add-ons bolted on at the end.

Why it matters

Accessibility is first a matter of inclusion: a significant share of the population has a disability, and an inaccessible site simply excludes them. It is increasingly a legal requirement, with real obligations and penalties in many jurisdictions. And it benefits everyone: captions help in noisy places, good contrast helps in bright sunlight, clear structure and keyboard support improve usability for all, and the same semantic markup that helps screen readers also helps SEO. Accessible sites tend to be better sites, full stop.

Common mistakes

Frequent failures include images without text alternatives, poor colour contrast, forms without proper labels, content that only works with a mouse, using colour alone to signal meaning, auto-playing media, and treating accessibility as a final checkbox rather than a design principle. Relying only on an automated checker is another trap, since many issues can only be found through real keyboard and screen-reader testing.

Web accessibility at BeBranded

Accessibility is part of building a site properly, not an afterthought. In our design and build work we use semantic structure, sufficient contrast, keyboard-friendly components and text alternatives from the start, aiming at recognised standards like WCAG and, where relevant, the RGAA. The result is a site more people can use, that reduces legal risk, and that tends to perform better in search too, since the same clean structure serves both assistive technology and search engines.
