In plain English

What this means for visitors

The scan found issues that may cause problems for visitors with disabilities, such as screen reader users or those who navigate with keyboards. For example, some interactive elements are missing necessary parts, and hidden content can still be accessed, which can be confusing. To improve accessibility, start by fixing the critical issue, which is likely causing the most significant problems. Automated scans like this one catch many issues, but not all, so further review is recommended to ensure the site is usable for everyone.

Findings

3 issue types found on the homepage

Each item is one failing rule; the count shows how many elements on the page trigger it. Severity follows axe-core impact levels.

#1CriticalWCAG 1.3.11 elementRule details ↗

ARIA widget is missing required parts

A menu/tab/list widget is incomplete, so assistive technology can't operate it.

Who it affects

Blocks a task outright for some visitors (for example an image-only flyer with no text, or a form field with no label).

First fix

Fix the widget markup or update the plugin that generates it.

#2MajorWCAG 4.1.28 elementsRule details ↗

Hidden content can receive focus

Keyboard users land on elements that screen readers say don't exist.

Who it affects

Makes a task significantly harder (low contrast, links with no name, missing frame titles).

First fix

Remove tabindex from hidden elements or don't hide focusable content with aria-hidden.

#3MajorWCAG 2.5.82 elementsRule details ↗

Touch targets are too small

Small links and buttons are hard to tap for people with motor impairments.

Who it affects

Makes a task significantly harder (low contrast, links with no name, missing frame titles).

First fix

Make clickable targets at least 24×24 CSS pixels or add spacing.

Severity guide

How to read the counts

Critical

Blocks a task outright for some visitors (for example an image-only flyer with no text, or a form field with no label).

What this grade does and does not cover

  • Covers: the public homepage only, loaded once in a desktop browser, tested with axe-core against WCAG 2.2 Level A and AA rules (a superset of the WCAG 2.1 AA standard in the DOJ rule).
  • Does not cover: inner pages, PDFs and documents, logged-in portals, video captions, alt-text quality, keyboard usability of custom widgets, or anything that needs a human judgment.
  • A grade is a monitoring signal, not a legal assessment or certification. How we score.
