<a href="https://blockaccessibilitychecks.com/" rel="nofollow ugc">Block Accessibility Checks</a> is a comprehensive WordPress plugin that proactively prevents accessibility issues in your content before they reach your audience. Designed for the Gutenberg block editor, it provides real-time validation that ensures your images, buttons, tables, headings, galleries, and post meta fields meet WCAG (Web Content Accessibility Guidelines) requirements.
Unlike reactive accessibility tools that scan published content, this plugin catches problems during the editing process—giving immediate visual feedback and preventing publication of content with critical accessibility errors. Content creators get clear guidance on what needs fixing, while developers can extend the system with custom checks for any block type or post meta field.
Whether you’re a content creator ensuring your posts are accessible, a developer building accessible blocks, or an organization maintaining compliance standards, Block Accessibility Checks provides the tools you need to create inclusive content effortlessly.
Key Features:
<ul>
<li>Real-time Visual Feedback – See accessibility issues instantly with color-coded borders around problematic blocks and detailed error messages in the block inspector panel</li>
<li>Smart Publishing Control – Prevents publication of content with critical accessibility errors while allowing warnings with user awareness</li>
<li>Comprehensive Block Coverage – Built-in checks for images, buttons, tables, headings, and galleries with multiple validation rules per block type</li>
<li>Post Meta Validation – Validate required post meta fields with real-time feedback, automatic post locking for errors, and seamless integration with block validation</li>
<li>Advanced Heading Validation – Document-wide hierarchy checking prevents skipped heading levels and ensures proper content structure</li>
<li>Intelligent URL Validation – Real TLD validation using the Public Suffix List ensures only legitimate domains are accepted</li>
<li>Configurable Settings – Granular control over each check’s severity (error/warning/disabled) with an intuitive admin interface for both block and meta validation</li>
<li>Issue Categorization – Clear distinction between accessibility issues and validation errors for better understanding</li>
<li>Developer-Friendly API – Comprehensive hooks and filters system for registering custom accessibility checks for blocks and post meta fields</li>
<li>External Plugin Support – Works seamlessly with custom blocks from third-party plugins and themes, with automatic settings page integration</li>
</ul>
How It Works:
The plugin provides immediate feedback as you edit content. When accessibility issues are detected in blocks or required meta fields, they are highlighted with visual indicators and detailed messages explain how to fix the problems. Critical errors prevent publishing until resolved, while warnings allow publication with user acknowledgment.
Built-in Accessibility Checks:
<ul>
<li>Button Blocks – Ensures buttons have descriptive text content and valid link destinations with real URL validation</li>
<li>Image Blocks – Requires alt text (unless marked decorative), validates length, prevents caption duplication, and detects non-descriptive patterns</li>
<li>Table Blocks – Requires proper headers or captions for screen reader navigation</li>
<li>Heading Blocks – Validates proper heading hierarchy (no skipped levels), ensures appropriate first heading level, and configurable heading level restrictions</li>
<li>Gallery Blocks – Applies comprehensive image accessibility checks to all gallery items</li>
<li>Post Meta Fields – Validate required custom fields with server-side and client-side validation, automatic post locking, and visual feedback in the editor</li>
</ul>
Perfect For:
<ul>
<li>Government websites requiring WCAG compliance</li>
<li>Educational institutions with accessibility mandates</li>
<li>Businesses committed to inclusive web content</li>
<li>Developers building accessible WordPress themes and plugins</li>
<li>Content teams who want accessibility guidance built into their workflow</li>
</ul>

<h3>More than an Accessibility Widget or an Overlay Widget</h3>
Accessibility Tool Kit is not an accessibility tool that adds a widget or an overlay on your website front-end. This web accessibility WordPress plugin aims to remediate accessibility issues and fix accessibility barriers at the code level without compromising the performance of the website. The plugin does not add JavaScript to modify how people with disabilities and users of assistive technologies interact with your website.
This web accessibility WordPress plugin helps you:
<ul>
<li>Improve WordPress accessibility compliance without needing to code</li>
<li>Strengthen screen reader accessibility with better markup and ARIA attributes</li>
<li>Ensure accessible links and forms sitewide</li>
<li>Make your site usable for keyboard-only navigation</li>
<li>Provide mobile zoom and readability enhancements for on-the-go visitors</li>
</ul>
<h3>Accessibility Tool Kit Features for your WordPress Web Accessibility Goals</h3>
Website accessibility is crucial because around 15% of the world’s population—approximately 1 billion people—live with some form of disability. Ensuring your website is accessible and compliant with standards like WCAG (Web Content Accessibility Guidelines) level A, AA, and AAA, and legal frameworks such as the ADA (Americans with Disabilities Act), Section 508 of the Rehabilitation Act, and the EAA (European Accessibility Act) makes it inclusive for people with diverse needs.
Accessibility is a necessity for some—and useful for all.
Below are the core features of the plugin that will help you reach your WordPress website accessibility goals: 
* [New] Accessibility Checker – adds a front-end scanning widget to identify potential accessibility issues on your WordPress site. The checker detects WCAG violations such as missing labels, poor contrast, or improper heading structure, helping you understand where improvements are needed. 
* Accessibility toolbar – to help users with disability make necessary adjustments on your website to meet their unique accessibility needs. 
* Accessibility Statement Generator – easily generate and add an accessibility statement to your website per various laws, like the European Accessibility Act (EAA) or the Americans with Disability Act (ADA). 
* Improved readability – ensures screen readers interpret text and language correctly. 
* Logical keyboard navigation – maintains natural tab flow and focus throughout the page. 
* Skip to content – lets users jump straight to the main content using the keyboard. 
* Visible focus indicators– highlight the active element clearly during keyboard use. 
* Clear and meaningful labels – adds helpful names to elements for better screen reader support. 
* Mobile-friendly zoom – allows users to zoom on mobile without breaking the layout. 
* Accessible links – makes links stand out clearly and visibly without relying on colour. 
* Predictable link behaviour – avoids unexpected new tabs or windows. 
* Link opening notices – alerts users when a link opens in a new tab or window. 
* Labelled form fields – ensures every input field has a proper label for accessibility. 
* Accessible search fields – adds clear labels to search bars for easier use.
<h3>📌 [Feature Update] Accessibility Checker for WordPress</h3>
The WordPress Accessibility Checker feature in Accessibility Tool Kit adds a front-end scanning widget that allows administrators to identify potential accessibility issues directly on the website. This feature helps admins visually understand where accessibility improvements are needed without altering the appearance or functionality of the live site. 
Only users with administrator access can view and use the widget. The checker runs in the background and detects accessibility violations based on the WCAG 2.1 standards, providing a clear summary of issues on each page. 
Key Highlights: 
* Adds a front-end scanning widget visible only to administrators. 
* Detects WCAG violations such as missing alt text, low color contrast, improper heading hierarchy, and unlabeled form fields.
<ul>
<li>
Provides on-page visual indicators to pinpoint accessibility issues directly within the site layout.
</li>
<li>
Displays a summary of detected issues in an easy-to-read panel for quick reference.
</li>
<li>
Does not modify or overlay your website’s content or design; instead, it analyzes the underlying code to identify areas that need attention.
</li>
</ul>
<h3>Accessibility Toolbar</h3>
Enhance your website’s accessibility with our brand-new Accessibility Toolbar. An interactive widget designed to make your site more inclusive and user-friendly.
With this toolbar, website admins can easily test accessibility compliance and give visitors greater control over their browsing experience. The toolbar appears as a small, customizable widget on the front end of your website and offers several helpful tools:
<ul>
<li>Adjustable Font Size: Users can increase or decrease text size across your site for better readability.</li>
<li>
Color Contrast Options: Switch between different color contrast modes to improve visibility and accessibility. This will also help you quickly test how the site performs under different visual conditions, particularly for users with low vision or color blindness.
</li>
<li>
Greyscale Mode: View your website in greyscale to test visual contrast and ensure all elements are distinguishable.
</li>
</ul>
Admins can use this feature to evaluate their site’s accessibility, or choose to keep it enabled so visitors can personalize how they view content. 
By empowering both administrators and end-users, the Accessibility Toolbar help in ensuring that everyone can engage with your content comfortably and effectively.
Accessibility Statement Generator ==
An accessibility statement is a public declaration of your website’s commitment to accessibility. 
It informs visitors about the steps you have taken to make your content accessible and what measures are in place to support users with disabilities.
With the Accessibility Statement Generator in Accessibility Tool Kit by WebYes, you can:
<ul>
<li>Quickly create and publish an accessibility statement on your site</li>

<li>Show compliance with legal frameworks like the ADA, Section 508, and the European Accessibility Act (EAA)</li>
<li>Build trust with users by clearly communicating your accessibility efforts</li>
</ul>
Publishing an accessibility statement not only improves user confidence but also helps reduce the risk of accessibility-related legal complaints by showing that you are actively working toward compliance.

<li>Section 508</li>
<li>EN 301 549</li>
<li>ARIA 1.1 Authoring Practices</li>
</ul>
Disclaimer: While Accessibility Tool Kit helps address many common accessibility issues, it does not guarantee 100% compliance with WCAG standards, ADA, or other accessibility laws. Some elements, such as writing meaningful image alt text, ensuring link purpose clarity, and maintaining proper content hierarchy, still require manual review and human judgment.
For full legal compliance, a comprehensive accessibility audit and remediation process is recommended.
