Think about accessibility as the bridge that unites people with technology. A very substantial portion of the population of the world is locked out when designs do not cater to users who have disabilities, be they visual, auditory, motor, or cognitive.
The moral argument is simple: access to digital content is a human right. Legally, the force is mounting, with laws such as the, Americans with Disabilities Act(ADA) Section 508, and the EU Web Accessibility Directive leading to lawsuits and expensive fines for non-compliance. There is a strong business case alongside ethics and compliance. Nobody’s usability is left behind with accessible design.
High color contrast benefits outdoor users, keyboard shortcuts streamline workflows for power users, and captions help commuters in noisy spaces. Accessibility builds customer loyalty, opens up your audience, and boosts SEO. Aside from being the right thing to do, businesses who opt for accessibility are also getting a competitive edge.
