How to Create an Accessible UI with Bootstrap

Did you know that 15% of the global population lives with a disability? That’s over a billion users who might not be able to use your website if it’s not accessible.

What if your beautifully designed interface is pushing users away just because it's not readable by screen readers or hard to navigate by keyboard?

The good news: Bootstrap, one of the most popular front-end frameworks, already has built-in accessibility features—you just need to know how to use them correctly.

Let’s dive into how you can craft a user interface that works for everyone—and doesn’t require you to rebuild your UI from scratch.

Why Accessibility Matters More Than Ever

  • Legal compliance: Avoid lawsuits (like the famous Domino's Pizza case).

  • SEO boost: Search engines love accessible websites.

  • Wider reach: More inclusive = more users.

  • Better UX for all: Accessibility improvements benefit everyone, not just people with disabilities.


Start Here: Semantic HTML Comes First

Before even touching Bootstrap classes, ensure you're using proper semantic HTML.

Instead of:

<div onclick="goHome()">Click here</div>
Enter fullscreen mode Exit fullscreen mode

Use:

<button onclick="goHome()">Click here</button>
Enter fullscreen mode Exit fullscreen mode

It’s not just about looks—semantic HTML gives assistive tech the info it needs.

1. Use Bootstrap Components That Are Already Accessible

Bootstrap’s components like modals, dropdowns, and tooltips are built with accessibility in mind.

For example:

<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
  Launch modal
</button>

<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      ...
    </div>
  </div>
</div>
Enter fullscreen mode Exit fullscreen mode

Notice the aria attributes like aria-labelledby and aria-hidden. Bootstrap adds these automatically to ensure screen readers can interpret them correctly.

2. Always Include ARIA Labels Where Necessary

Not every component includes labels by default. For custom components or icons, manually add ARIA labels.

<a href="#" aria-label="Close" class="btn-close"></a>
Enter fullscreen mode Exit fullscreen mode
  • aria-label tells screen readers what the button does, even if there's no text.
  • Use aria-hidden="true" if an element should be ignored by screen readers.

3. Ensure Sufficient Color Contrast

Bootstrap doesn’t automatically ensure that your text color contrasts well with the background. Use tools like:

Tips:

  • Stick to bg-light and text-dark or bg-dark and text-light.
  • Avoid placing text over background images without contrast layers.

4. Make All Interactive Elements Keyboard-Friendly

Users should be able to tab through your site using the keyboard. Focus management is crucial.

Use tabindex="0" for custom focusable elements:

<div tabindex="0">Focusable Div</div>
Enter fullscreen mode Exit fullscreen mode

Also, don't forget to style :focus states:

:focus {
  outline: 2px solid #0d6efd;
  outline-offset: 2px;
}
Enter fullscreen mode Exit fullscreen mode

5. Don't Hide Content Improperly

Avoid using display: none; or visibility: hidden; to hide important content from screen readers.

Instead, use:

<span class="visually-hidden">Screen reader only text</span>
Enter fullscreen mode Exit fullscreen mode

Bootstrap provides .visually-hidden (formerly .sr-only) to help hide content visually while keeping it accessible.

6. Form Accessibility: Labels and Feedback

Always pair form controls with <label> elements.

✅ Good:

<label for="email">Email address</label>
<input type="email" id="email" class="form-control" />
Enter fullscreen mode Exit fullscreen mode

❌ Bad:

<input type="email" placeholder="Email" class="form-control" />
Enter fullscreen mode Exit fullscreen mode

Also, provide accessible validation feedback:

<div class="invalid-feedback">
  Please provide a valid email.
</div>
Enter fullscreen mode Exit fullscreen mode

Bootstrap toggles this visibility with is-invalid or is-valid classes based on form state.
