The Equalize Digital Accessibility Checker plugin adds a new NASA-funded frontend highlighting feature

Accessibility Checker, a WordPress plugin to ensure accessibility, supporting an inclusive web and actively contributing to the community.

Equalize Digital, a WordPress accessibility products and services company, added a new frontend highlight feature to its free accessibility checker plugin, used to audit self-hosted sites. The feature was commissioned and funded by the National Aeronautics and Space Administration (NASA), through Equalize Digital's consulting work on the new NASA websites.

Equalize Digital is a Certified B Corporation, WordPress VIP Agency Partner, and corporate member of the International Association of Accessibility Professionals (IAAP), which is committed to creating a world where all people have equal access to products and tools on the web, regardless of their abilities. Their team has been building custom WordPress websites, themes, and plugins since 2010, and has been working on government, university, and corporate websites since 2016. They created Accessibility Checker after hearing from their customers about the challenges they face maintaining accessibility on their websites. They say they are constantly working and working to improve Accessibility Checker and are contributing to the WordPress community through education and support.

NASA recently launched the beta version of its WordPress-powered main site, which WordCamp US attendees could hear about next week at team sessions, including Friday's main address: For All Users: web modernization NASA and WordPress” and another presentation titled “Practice with NASA's new digital platform”.

Equalize Digital has been engaged to perform accessibility testing, user testing with screen reader users and provide accessibility governance recommendations.

As part of the contract for these services, they also commissioned us to develop this feature for the plugin, they have an enterprise license but we decided in collaboration with them to make it a feature in the plugin for free so that everyone could benefit from it, not a feature just for payment. They were actually very interested in this because it is part of their mission to give something back to humanity.

said Amber Hinds, CEO of Equalize Digital.

Before developing the frontend highlighting feature, the accessibility checker plugin only had reports within the post edit screen, resulting in near-indecipherable output for less technical users not used to reading HTML.

The new frontend highlighting feature makes the accessibility report output much more accessible for users who may not be developers. Adds a “view on page” link next to each issue found in the report, which takes users to the frontend where the item in question is highlighted with a pink dotted box. It also shows a panel that explains the problem in an easier to understand way and how to fix it.

The admin report has been updated to be easier to read. A new image column displays all images related to issues, and the Actions column includes a “View on Page” link that takes you to the highlighted issue in the frontend.

Hind said his team is working on making the tool more friendly to content creators and not just a developer tool. The plugin will remain on the NASA website to help their team as they add and edit content over time.

In the future, we are planning to add the ability to jump to item in the block editor. It's a bit tricky because we scan the whole page, not just the content area; therefore, we need to exclude elements created by other parts of the editor or theme.

Hinds said.

Thanks to funding from NASA, the new frontend highlighting feature is available to users in the free version of the plugin on

Our goal is to make accessibility testing easier for every WordPress user, not just developers, Accessibility Checker was developed to include a robust free version with that in mind. We want to standardize the creation of websites that work for people with disabilities, and we've been excited to work with NASA to make accessibility test reports easier for non-developers to understand and act on. Adding this feature to the free plugin went without saying for us. We look forward to seeing more WordPress website owners find and fix accessibility issues on their websites.

said Amber Hinds, CEO of Equalize Digital.
