Designing for Accessibility

You’ve learned how to build interfaces that look great, respond quickly, and work across devices. But let’s take a moment to ask: Who are you building for?

If your answer doesn’t include everyone, then it’s time to talk about accessibility.

Accessibility — often shortened to a11y — is about designing products that work for all users, including those with disabilities. That includes people who:

  • Use screen readers because they’re blind or have low vision
  • Navigate with keyboards instead of a mouse
  • Can’t hear audio or rely on captions
  • Experience cognitive or motor challenges

Let’s dive into why accessibility matters, and how you can start making your interfaces more inclusive today.


🌍 Why Accessibility Matters

There’s a common misconception that accessibility is a “nice to have.” But in reality:

  • Over 1 billion people worldwide live with some form of disability
  • Accessibility helps everyone — captions in noisy places, high contrast in sunlight, keyboard shortcuts for power users
  • In many regions, it’s legally required (e.g., WCAG, ADA, EN 301 549)

But beyond compliance, it’s about empathy. As creators, we want people to enjoy our apps — not struggle with them.

“When we design for disability, we often solve problems for everyone.” — Microsoft Inclusive Design

📚 Also revisit our discussion on UI vs UX — accessibility is deeply tied to user experience, not just interface aesthetics.


🧰 Tools and Techniques

You don’t need to be an expert to start designing accessibly. Here are a few essentials to get you started:

📋 Semantic HTML

Use tags that describe meaning:

<!-- Good -->
<button>Submit</button>

<!-- Not so good -->
<div onclick="submitForm()">Submit</div>

This helps screen readers and other assistive tech understand your UI.

⌨️ Keyboard Navigation

Make sure your app is usable with a keyboard:

  • Can you Tab through all interactive elements?
  • Do Enter or Space trigger buttons or links?
  • Are focus states visible?

🎨 Color & Contrast

Ensure sufficient contrast between text and background:

🗣️ ARIA Attributes (Used Sparingly)

ARIA helps where HTML falls short:

<div role="alert">Form submission failed.</div>

But use built-in elements first — ARIA is a helper, not a crutch.

📱 Mobile Accessibility

  • Support dynamic text resizing
  • Don’t trap users in modal dialogs or swipe-only flows
  • Test with screen readers: VoiceOver (iOS), TalkBack (Android)

🧪 Your Challenge

Take one of your earlier projects — maybe the subscription form or habit tracker — and:

  1. Add clear labels and instructions
  2. Ensure keyboard accessibility
  3. Check color contrast
  4. Try navigating with a screen reader or Tab key only

Bonus: Add a “skip to content” link at the top of the page.

Accessibility isn’t a checklist — it’s a mindset. Every choice you make, from button text to layout structure, impacts someone’s ability to use your app.

By building inclusively, you’re building better for everyone.
