Web Accessibility (a11y)

Making the Web for Everyone: Why Web Accessibility (a11y) Matters

When we think about the internet, we often imagine it as a place of endless opportunity — a global commons where anyone can connect, create, and learn. But for millions of people living with disabilities, that promise of accessibility is often left unfulfilled. That’s where web accessibility (commonly written as a11y) comes in.

What is Web Accessibility?

Web accessibility means designing and building websites, apps, and digital tools so that they’re usable by everyone, regardless of ability. This includes people with:

• Visual impairments (blindness, low vision, color blindness)
• Hearing impairments (deafness, hard of hearing)
• Motor disabilities (limited fine motor control, paralysis)
• Cognitive and learning disabilities (dyslexia, memory issues, ADHD)

An accessible web experience ensures that content is perceivable, operable, understandable, and robust (known as the POUR principles). Whether it’s using a screen reader, navigating with only a keyboard, or having clear, understandable content, accessibility empowers people to engage fully online.

Why Accessibility Matters

1. It’s About Inclusion

At its core, accessibility is about human rights and inclusion. The internet should be a place where everyone belongs — and designing with accessibility in mind ensures no one is left out.

2. It’s the Law

In many countries, including the U.S. (ADA), Canada (AODA), and the EU (EN 301 549), digital accessibility is not just a nice-to-have — it’s a legal requirement. Non-compliance can lead to lawsuits and fines.

3. Better UX for Everyone

Good accessibility practices often lead to better overall user experiences. Clear navigation, readable fonts, and thoughtful contrast help everyone, not just those with disabilities. Ever used captions while watching a video in a noisy place? That’s accessibility in action.

4. SEO Boost

Accessible websites tend to rank better in search engines because features like alt text and semantic HTML help crawlers understand content more effectively.

Quick Wins to Improve Accessibility

• Use semantic HTML: Elements like <nav>, <header>, <main>, and <footer> give structure and meaning.
• Provide alt text for images: Descriptions help screen reader users understand visual content.
• Ensure sufficient color contrast: Tools like the WebAIM contrast checker can help.
• Add captions and transcripts to media.
• Make interactive elements keyboard-friendly: All buttons, forms, and links should be usable without a mouse.
• Use clear, simple language: Write in a way that’s easy to understand.

Accessibility is a Journey

Web accessibility isn’t a one-time checklist — it’s an ongoing practice of empathy, learning, and improvement. Technologies change, user needs evolve, and our understanding deepens over time.

The best way to start? Include accessibility from the very beginning of your design and development process. Test early, test often, and most importantly, listen to the voices of people with lived experience.

By embracing a11y, you’re not only following best practices — you’re making the web a better, more inclusive place for everyone.
