WCAG

What is WCAG?

The WCAG (Web Content Accessibility Guidelines) is a set of technical recommendations published by the W3C to make web content accessible to people with disabilities (visual, auditory, motor, cognitive). Organized around four principles — Perceivable, Usable, Understandable, and Robust (FOR) — WCAG defines compliance criteria divided into three levels: A, AA, and AAA.

Why is WCAG important for websites in 2025?

The European Accessibility Act makes WCAG 2.1 Level AA compliance mandatory for many digital services as of June 2025. Beyond the legal obligation, accessibility improves UX for all users, reduces the bounce rate and can have a positive impact on SEO (semantic structure, alt text, contrasts). Ignoring accessibility is exclude about 15% of the world's population.

What are the most common WCAG criteria to meet?

The criteria most frequently checked during the audit include: sufficient color contrasts (minimum 4. 5:1 for normal text), the presence of alt attributes on all images, functional keyboard navigation if possible, forms with associated labels, unique and descriptive page titles, and the absence of content that flashes more than 3 times per second. These criteria can be verified using tools like Axe, Wave or Lighthouse.

How to integrate WCAG into a Webflow project?

Webflow offers native features to facilitate WCAG compliance: ARIA attributes accessible via element settings, management of semantic roles (nav, main, footer), alt text on CMS images, and visible focus on interactive elements. Points of attention specific to Webflow include animations (to be deactivated if prefers-reduced-motion is enabled), modals and dropdowns (trap focus management), and the logical reading order in the DOM.
