Accessibility (a11y)

What is accessibility (a11y)?

Accessibility, often shortened to a11y (the 11 letters between the a and the y), is the practice of building digital products that people with disabilities can actually use. That includes people who are blind or have low vision, people who are deaf or hard of hearing, people with motor impairments, and people with cognitive differences. The same work also helps people in temporary or situational contexts, like a broken arm or bright sunlight on a phone screen.

In practice it covers things like keyboard navigation, screen reader support, sufficient colour contrast, captions for video, and clear focus states. A form that only works with a mouse locks out anyone who navigates by keyboard, which is a common and avoidable a11y failure. The Web Content Accessibility Guidelines (WCAG) set the standard most teams and regulations measure against.

Accessibility is increasingly a legal requirement, not a nice-to-have. The European Accessibility Act, the ADA in the United States, and similar laws elsewhere put real obligations on digital products. It overlaps with inclusive design, but the two are distinct: inclusive design is the broader mindset, while accessibility is the measurable practice of removing barriers for disabled users.

Accessibility at Dallonses

Accessibility is part of how we build, not a pass we run at the end. We bake it into design and development from the first wireframe, because retrofitting an inaccessible product costs far more than getting it right while it is being built. Semantic markup, keyboard support, and contrast checks are baseline, not extras.

Our web accessibility work targets WCAG compliance and pairs it with inclusive design, so the result holds up for real users and for an audit. We test with screen readers and keyboard-only flows, not just automated scanners that miss most real issues. When a client operates in a regulated market, we help them meet the standard and document it. Accessible websites reach more people and rank better, so the case for getting it right is practical as well as ethical.

Need a product that works for everyone and stands up to an accessibility audit? Let's get it right from the start.
