Plasmic Accessibility Checklist 2026 | WCAG 2.1 AA & EAA Compliance
Last updated: 2026-07-19
Plasmic is a visual page builder that lets designers and marketers assemble pages in a drag-and-drop editor while developers integrate the output into a React, Next.js, or Gatsby codebase or pull it through a headless API. That hybrid model shapes where accessibility succeeds or fails. Because Plasmic gives you full control over the element tree, nothing forces the right HTML tag onto a box: a heading dropped in visually can render as a plain div, a clickable card can be a styled container with an onClick handler instead of a real link or button, and an image element can ship with no alternative text field filled in. At the same time, Plasmic's strength is code components, where developers register their own accessible React components for the visual editor to use, which means a well-built component library can guarantee good semantics that non-technical editors then reuse safely. Dynamic content adds another layer: pages bound to Plasmic CMS data or an external API generate repeated markup from a template, so a single missing alt binding or a heading level hard-coded in a loop multiplies across every record. Design tokens and theme styles centralize color and typography, which is powerful for fixing contrast once, but also means a poorly chosen brand color repeats everywhere until corrected at the token level. With the European Accessibility Act now in force and procurement teams asking for conformance evidence, Plasmic teams need both an accessible component library and editorial discipline in the visual editor. This checklist covers the issues that appear most often in Plasmic projects and how to fix them in both the editor and your code.
Common Accessibility Issues
In the Plasmic editor a text block defaults to a generic tag, and designers often style text to look like a heading without changing the HTML tag to h1-h6. Screen reader and keyboard users rely on a real heading outline to navigate, so pages that look structured but ship as a flat run of divs and spans are very hard to scan.
In the element's settings set the correct HTML tag (h1 through h6) so visual size maps to semantic level, keep a single h1 per page, and avoid skipping levels. Build reusable heading components or slots so editors pick a semantic level rather than a font size, and review the heading outline of key pages before publishing.
Image elements added in the editor, or images pulled from Plasmic CMS and external data, are frequently published with an empty alt attribute because the alt field was left blank or never bound to a CMS column. Screen reader users lose any information the image carries, and in dynamic lists the omission repeats for every record.
Fill the alt field on every meaningful image, and for data-bound images bind the alt attribute to a dedicated CMS text field so each record supplies its own description. Mark purely decorative images with an empty alt so assistive technology skips them, and require an alt field on any custom image code component you register.
Plasmic makes it easy to attach an onClick interaction or a link to any box, so entire cards, tiles, and 'buttons' are often plain containers with a click handler. These are not reachable by keyboard, expose no button or link role, and give no focus indicator, leaving keyboard and screen reader users unable to operate them.
Use the Link element for navigation and a real button element for actions rather than attaching click handlers to generic boxes, so the control is focusable, operable with Enter or Space, and correctly announced. For complex interactive components, register an accessible React code component that renders native interactive elements and manages focus and roles.
Interactive patterns such as carousels, tabs, accordions, modals, and menus are commonly added as custom code components or third-party libraries. When these do not implement the expected ARIA roles, states, and keyboard behavior, they are announced incorrectly or cannot be operated without a mouse.
Build interactive code components on native elements and follow the WAI-ARIA Authoring Practices for each pattern, implementing roles, states such as aria-expanded and aria-selected, focus management, and the expected keyboard interactions. Audit any third-party React component you register in Plasmic for accessibility before exposing it to editors.
Plasmic projects define colors and typography as design tokens and theme styles chosen for brand rather than legibility. Button text, links, placeholder text, and text over images often fall below the required 4.5:1 ratio, and because the values come from shared tokens the failure repeats across every page that uses them.
Audit your Plasmic design tokens against WCAG contrast requirements and adjust the accessible variants centrally so the fix propagates everywhere. Define compliant foreground and background pairings for buttons, links, and overlays, and document them so future pages and components reuse accessible colors.
Pages that filter lists, load more items, or submit forms through Plasmic interactions and data operations update the DOM without a full page reload. These changes are silent to assistive technology by default, so screen reader users are not told that results changed, that a form succeeded, or that more content loaded.
Wrap dynamically updated regions in an element with an aria-live value of polite (or assertive for critical messages) and announce the outcome, for example 'Showing 12 results'. After form submission move focus to a success or error message with an appropriate role so the change is both announced and reachable, and ensure loading states are conveyed to assistive technology.
Plasmic-Specific Tips
- Invest in an accessible code component library: register your own React components with correct semantics, labels, and keyboard support so non-technical editors reuse accessible building blocks instead of raw boxes.
- Set the correct HTML tag on every element in the editor; because Plasmic does not force semantics, headings, lists, links, and buttons must be assigned deliberately rather than styled to merely look right.
- Bind image alt text to a dedicated field in Plasmic CMS so data-driven pages and lists supply a real description for each record instead of publishing empty alt attributes at scale.
- Fix contrast and focus styles at the design-token and theme level so a single correction propagates to every page and component that consumes those tokens.
- Preserve a visible keyboard focus indicator; custom styling often removes default outlines, so add a clear focus-visible style that meets contrast requirements across interactive elements.

A browser extension that visualizes a page's heading outline, making it easy to spot the missing and skipped heading levels that result when Plasmic text is styled visually without setting the correct semantic tag.
NVDA Screen Reader
A free Windows screen reader for testing Plasmic forms, custom components, and dynamic lists the way an assistive technology user experiences them, surfacing missing labels, unannounced updates, and inoperable controls.
