Webflow Accessibility Checker

Accessibility on Webflow

Webflow is unusual among website builders in that it gives designers direct control over the underlying HTML: you can assign real heading levels, landmark elements and ARIA attributes in the visual Designer, and Webflow supports :focus-visible styling out of the box.

The gap is almost always in how that control gets used. A div styled to look like a heading, an image imported without its alt text field filled in, or a custom interaction that steals keyboard focus will pass visually and fail an audit.

Webflow outputs proper semantic HTML, including heading, nav, main and landmark elements, when the correct element types are chosen in the Designer, and every image has a built-in alt text field. Most Webflow sites still fall short of full compliance, not because the platform is inaccessible, but because those choices are easy to skip during a build.

Common Accessibility Issues on Webflow Sites

• Styled divs instead of real headings

  Text boxes styled with heading-sized fonts, instead of an actual Heading element, look identical visually but are invisible to screen reader navigation.

• Empty alt text fields

  Webflow prompts for alt text on every image, but it is optional, and images imported or duplicated quickly often keep it blank.

• Custom interactions and animations

  Webflow’s interactions panel makes it easy to build scroll and click animations that move focus unpredictably or hide content from keyboard users.

• Embedded custom code

  Custom code embeds and third-party widgets (booking tools, chat, video players) bring their own accessibility issues that Webflow’s Designer has no control over.

• Color contrast in the style guide

  Brand color palettes chosen for visual design are not automatically checked against WCAG contrast ratios anywhere in the Designer.

How AccessBell Scans Your Webflow Site

1. Enter any public page. Paste the address of a page on your Webflow site into the scanner above. There is nothing to install: no plugin, no code snippet and no login.
2. We load it in a real browser. AccessBell opens the page in headless Chrome and runs its scripts, so it tests what your visitors actually see, including content added by your theme, apps or plugins.
3. We run the WCAG rules. The open-source axe-core engine checks the page against the standard you choose, and every result is mapped to the WCAG success criteria it affects.
4. You get a report in seconds. Each issue comes with the failing HTML and how to fix it. Our methodology explains exactly what runs and what still needs a person.

What's Included in Every Scan

• 63 automated rules for WCAG 2.2 Level AA, or presets for WCAG 2.1 AA, the ADA, Section 508 and EN 301 549
• Every issue ranked by severity, from critical to minor
• The WCAG success criteria each issue fails, which you can look up in our WCAG library
• The failing HTML, so you can find the element in your Webflow editor or code
• How to fix each issue, with a link to the rule's full documentation
• A list of checks that need a person to review, so nothing is missed
• Filters by WCAG version, level, principle, success criterion and severity

The free scan checks one page at a time. AccessBell Pro scans up to 500 pages per domain every day and alerts you when something changes.

How to Fix What the Scan Finds

1. Most fixes in Webflow are quick: swap a styled div for the correct Heading element, or fill in a missing alt text field, directly in the Designer.
2. Scan the published site, not just the Designer preview, since custom code and third-party embeds only run on the live page.
3. Run a free scan above on your homepage and a few key pages, fix issues starting with critical and serious, then rescan to confirm.
4. For ongoing protection, AccessBell Pro monitors up to 500 URLs per domain every day and alerts you when a theme, app or plugin update introduces a new issue.
