Webflow is a powerful visual web development platform used by designers and agencies to build custom websites without traditional coding. While Webflow produces clean HTML and gives users control over semantic elements, the platform's visual-first design approach means accessibility is often an afterthought. Under the EAA, Webflow sites serving EU consumers must meet EN 301 549 requirements.
Common Webflow accessibility issues
Missing semantic structure
Webflow makes it easy to build layouts with generic div blocks instead of semantic elements. Without intentional effort, Webflow sites often lack proper landmarks (nav, main, aside, footer) that screen readers depend on.
Interactions and animations lack accessibility
Webflow's powerful interactions engine creates animations, transitions, and dynamic effects that are often not accessible. Hover-triggered content, auto-playing animations, and scroll-based effects can create barriers for keyboard and screen reader users.
Custom form controls without ARIA
Webflow's form styler lets designers create visually custom form elements, but the underlying markup often lacks proper ARIA attributes, making custom selects, checkboxes, and radio buttons inaccessible.
Heading hierarchy driven by visual size
Designers frequently choose heading levels based on visual size rather than document structure - using h3 because it looks right, even when h2 is semantically correct. This breaks the heading hierarchy screen readers depend on.
CMS collection content without alt text
Webflow CMS collections make it easy to create hundreds of pages from a template, but if the collection template doesn't enforce alt text fields, every generated page will have missing alt text on images.
How Lumi works with Webflow
Lumi scans your published Webflow site - navigating through all pages including CMS collection pages, utility pages, and custom interactions. Our five engines catch accessibility issues in Webflow's generated HTML, including problems with custom interactions, CMS-generated content, and form implementations. Monitor continuously to catch issues introduced by design changes.
Webflow-specific WCAG gotchas
Webflow doesn't validate accessibility
The Webflow designer has no built-in accessibility checker. You can publish a site with critical accessibility failures without any warning from the platform.
CMS collections multiply issues
A single accessibility issue in a CMS collection template is replicated across every collection item page. One missing alt text field = hundreds of pages with missing alt text.
Custom code embeds are a blind spot
Webflow's custom code embeds (for third-party widgets, analytics, chat tools) inject HTML that Webflow has no visibility into. This markup is often completely inaccessible.

Frequently asked questions
Can Webflow sites be fully accessible?
Yes - Webflow produces clean HTML and gives designers control over semantic elements, ARIA attributes, and alt text. But accessibility requires intentional effort in Webflow; it doesn't happen automatically.
Does Webflow support ARIA attributes?
Webflow allows adding custom ARIA attributes through the element settings panel. However, most designers don't use these features, and Webflow doesn't guide users toward proper ARIA usage.
How do I fix heading structure in Webflow?
In the Webflow designer, select each heading element and change its tag (H1-H6) in the element settings panel. Choose heading levels based on document structure, not visual size - use CSS classes to control appearance independently.
