Make your Bubble app accessible to all users by adding ARIA labels, ensuring keyboard navigation works, maintaining sufficient color contrast, supporting screen readers, and testing with accessibility tools. This tutorial covers practical steps for meeting WCAG guidelines within Bubble's visual editor so your app is usable by everyone.
Overview: Designing for Accessibility in Bubble
This tutorial teaches you how to make your Bubble app accessible to users with disabilities. You will add semantic HTML attributes, configure keyboard navigation, ensure color contrast meets WCAG AA standards, and test your app with screen readers and automated tools. Accessibility is not just ethical but also improves SEO and opens your app to a wider audience.
Prerequisites
- A Bubble account with an existing app to improve
- Basic familiarity with the Bubble Design tab
- A screen reader installed for testing (VoiceOver on Mac, NVDA on Windows)
- A web browser with developer tools
Step-by-step guide
Add ARIA labels to interactive elements
Add ARIA labels to interactive elements
Select any button, link, or interactive element in the Design tab. In the element's Property Editor, scroll to the Appearance section and look for the Accessible label field (or add it via Settings, then Visual Settings, then ID attribute, then use an HTML element for ARIA). For buttons, set descriptive labels like Submit registration form instead of just Submit. For icon buttons without text, the ARIA label is critical since screen readers cannot interpret the icon. For images, add alt text in the image element's properties.
Pro tip: Never use Click here or Read more as accessible labels. Always describe the action or destination, such as View pricing plans or Download project report.
Expected result: Interactive elements have descriptive ARIA labels that screen readers can announce to users.
Ensure proper heading hierarchy with HTML elements
Ensure proper heading hierarchy with HTML elements
Screen readers use heading tags (h1 through h6) to navigate page structure. Bubble's Text element does not natively output heading tags. To fix this, use an HTML element where you need semantic headings. Write heading tags directly such as h1 for the page title, h2 for section headings, and h3 for subsection headings. Keep a logical hierarchy with no skipped levels (do not jump from h1 to h3). Use only one h1 per page.
1<h1 style="font-size:32px; font-weight:700; margin:0;">Dashboard</h1>2<h2 style="font-size:24px; font-weight:600; margin:16px 0 8px;">Recent Activity</h2>3<h3 style="font-size:18px; font-weight:600; margin:12px 0 4px;">Today's Tasks</h3>Expected result: The page has a proper heading hierarchy that screen readers can use to navigate the content structure.
Configure keyboard navigation for interactive elements
Configure keyboard navigation for interactive elements
Test your app by pressing the Tab key to move through interactive elements. Every button, link, input, and dropdown should be reachable via Tab. If an element is not focusable, add a tabindex attribute via an HTML element or the element's ID settings. Set tabindex to 0 for elements that should be in the natural tab order. For custom interactive groups (like a card that acts as a button), add a click workflow triggered by keyboard events using a Do when condition is true with the condition checking for key press. Ensure focus indicators are visible with a clear outline or border on focus.
Expected result: All interactive elements can be reached and activated using only the keyboard, with visible focus indicators.
Check and fix color contrast ratios
Check and fix color contrast ratios
WCAG AA requires a minimum contrast ratio of 4.5 to 1 for normal text and 3 to 1 for large text (18px+ or 14px bold). Open your browser's developer tools and use the color contrast checker, or visit webaim.org/resources/contrastchecker. Test your most common text and background color combinations. In Bubble, update colors in the Styles tab (for global styles) or on individual elements. Pay special attention to placeholder text in inputs, disabled button text, and text on colored backgrounds.
Pro tip: Create a Color Variable in Bubble's Styles tab for your accessible text color so you can update it globally if needed.
Expected result: All text meets WCAG AA contrast ratios of 4.5 to 1 for normal text and 3 to 1 for large text.
Add skip navigation and landmark roles
Add skip navigation and landmark roles
Add a Skip to main content link at the very top of your page using an HTML element. This link should be visually hidden but visible when focused (using CSS that moves it on-screen on focus). The link target should be the main content area. Also add ARIA landmark roles to major page sections using HTML elements: role navigation for your nav bar, role main for the content area, and role contentinfo for the footer. These landmarks help screen reader users jump between page sections.
Expected result: Screen reader users can skip the navigation and jump directly to main content. Landmark roles allow quick section navigation.
Test with a screen reader and automated tools
Test with a screen reader and automated tools
Turn on VoiceOver (Command + F5 on Mac) or NVDA on Windows and navigate through your app using only the keyboard. Listen to how each element is announced. Check that buttons describe their actions, images have meaningful alt text, and form inputs have associated labels. Then run an automated accessibility audit using the browser's Lighthouse tool (DevTools, then Lighthouse tab, then check Accessibility). Also try the axe DevTools extension for more detailed issues. Fix any errors and warnings the tools report.
Expected result: Your app scores above 90 on Lighthouse accessibility audit and screen reader navigation is logical and descriptive.

Why it's a problem: Relying solely on color to convey information
How to avoid: Always pair color with another indicator such as an icon, text label, or pattern. Show error text next to the red border saying This field is required
Why it's a problem: Removing focus outlines for aesthetic reasons
How to avoid: Keep or customize focus indicators. Use the focus-visible CSS pseudo-class to show outlines only for keyboard users, not mouse clicks
Why it's a problem: Using decorative images without empty alt text
How to avoid: For decorative images, add an empty alt attribute. For informative images, write descriptive alt text explaining the content
Best practices
- Test with a screen reader at least once before launching your app
- Maintain a contrast ratio of at least 4.5 to 1 for all body text
- Use semantic HTML headings (h1 through h6) in proper hierarchy via HTML elements
- Add descriptive ARIA labels to all icon buttons and interactive elements without visible text
- Ensure all form inputs have associated labels that screen readers can announce
- Provide a skip navigation link at the top of every page
- Test keyboard navigation by pressing Tab through your entire page to verify all interactive elements are reachable

Frequently asked questions
Does Bubble natively support accessibility features?
Bubble provides some basic accessibility support including form labels and tab navigation for native elements. However, for WCAG compliance you need to add ARIA attributes, semantic headings, and focus management using HTML elements and custom configurations.
What is the minimum contrast ratio required by WCAG?
WCAG AA requires 4.5 to 1 for normal text (under 18px) and 3 to 1 for large text (18px or larger, or 14px bold). WCAG AAA requires 7 to 1 for normal text.
How do I test accessibility without a screen reader?
Use Chrome's Lighthouse audit (DevTools then Lighthouse then Accessibility), the axe DevTools browser extension, or the WAVE browser extension. These tools identify most common accessibility issues automatically.
Can I make Bubble popups accessible?
Yes. Add role dialog and aria-modal true to the popup group via an HTML element. Trap focus inside the popup while it is open, and return focus to the trigger button when it closes.
Is accessibility legally required?
In many jurisdictions, yes. The ADA in the US, the Equality Act in the UK, and the European Accessibility Act all require digital services to be accessible. Lawsuits over web accessibility have increased significantly.
Can RapidDev help make my app fully accessible?
Yes. RapidDev can perform a comprehensive accessibility audit of your Bubble app and implement fixes including ARIA attributes, keyboard navigation, screen reader optimization, and WCAG AA compliance testing.
