How to Make Your Web App Accessible Without Breaking the UI

The Forgotten User

A few months ago, a friend of mine tried to register on a website for a government job application. He’s visually impaired and relies on a screen reader to navigate the internet.

The page looked beautiful—clean UI, smooth animations, modern layout.

But for him, it was just silence.
No labels. No keyboard support. No access.

That’s when it hit me: a web app is only as good as the number of people who can actually use it.

As developers, we often chase clean interfaces and cool features. But what good is a stunning UI if it ignores users who can’t interact with it?

Accessibility isn't a bonus feature—it’s a responsibility.

Why Accessibility Matters

• Legal requirement in many countries (ADA, WCAG compliance)

• Inclusive by default – helps people with disabilities, situational impairments, or temporary limitations (like a broken mouse or slow connection)

• SEO and performance benefits often come bundled with accessible code

  
  

Misconception: Accessibility Breaks the UI

Many developers hesitate to implement accessibility because they assume:

• It means “ugly” layouts

• It slows down delivery

• It’s only for big enterprises

This is a myth.
With the right approach, accessibility can enhance your user experience without compromising the visual design.

Technical Guide: Make It Accessible

1. Use Semantic HTML First

HTML already comes with built-in accessibility features:

• Use <button>, not <div onclick="">

• Use <label> for <input>

• Use structural tags like <nav>, <section>, <article>, <main>

Semantic HTML gets you most of the way there—it's the foundation for accessible web development.

2. ARIA Roles – Add, Don’t Replace

ARIA (Accessible Rich Internet Applications) attributes can enhance support for screen readers, but should be used with care:

• Examples: aria-label, aria-hidden, role="button", aria-expanded

• Use only when semantic HTML alone isn’t sufficient

• Misusing ARIA can actually harm accessibility

Example:

<div role="button" tabindex="0" aria-label="Submit form">Submit</div>

3. Color Contrast and Visual Clarity

Use tools like:

• WebAIM Contrast Checker

• Chrome Lighthouse Accessibility Audit

• Tota11y

Best practice:
Maintain a minimum contrast ratio of 4.5:1 for normal text to ensure readability for all users.

4. Keyboard Navigation is Key

Your application should be fully navigable without a mouse.

• Use tabindex="0" for interactive elements

• Implement clear :focus-visible styles

• Avoid keyboard traps—users should always be able to tab out of modals or dropdowns

5. Screen Reader Testing

Test your application using screen readers like:

• NVDA (Windows)

• VoiceOver (Mac)

• ChromeVox

Pay special attention to:

• Dynamic content updates (aria-live)

• Form validation and error handling

• Modal dialogs

• Interactive elements such as buttons and links

  
  

Developer Accessibility Checklist

• Semantic HTML tags used appropriately

• Proper form labels and clear error messages

• Focus management in dynamic components like modals

• ARIA roles used only when necessary

• Minimum contrast ratio of 4.5:1 for text

• Keyboard-friendly navigation throughout

• Alt text provided for all meaningful images

• Avoid flashing animations or motion that may trigger discomfort

  
  

Final Thought

Accessibility isn’t about limiting your creativity or design—it’s about expanding usability.
Design for everyone, and your product becomes better for everyone.
