No landmarks detected
Screen reader users have no way to navigate by region.
Screen reader users cannot quickly navigate to the primary content. Wrap your main content in <main>.
Without a <main> landmark, screen-reader users can't skip past the navigation to the page content — every page starts with re-reading the menu.
Learn more ▾ ▴
The <main> element marks the page's primary content area. Assistive tech offers a 'jump to main' shortcut — but only if <main> exists. Without it, every page navigation forces re-reading the header. Wrap your primary content in a single <main>.

Add a skip link as the first focusable element so keyboard users can bypass repeated navigation.
Without a skip-nav link, keyboard users tab through every nav item before reaching content — every page, every visit.

WCAG 2.4.1 (Bypass Blocks) requires a mechanism to skip past repeated content. The standard implementation is a 'Skip to main content' link that's the first focusable element, visually hidden until focused. Three lines of HTML + four of CSS.

Accessibility
These checks highlight opportunities to improve the accessibility of your web app. Automatic detection can only detect a subset of issues and does not guarantee the accessibility of your web app, so manual testing is also encouraged.
Contrast
Low-contrast text is difficult or impossible for many users to read. Learn how to provide sufficient color contrast.
Performance issues directly impact user engagement and conversion rates.
| Failing Elements |

Matrix div.RootView > div.footer > p > a |
GitHub project div.footer > ul.links > li > a |
Add your app div.footer > ul.links > li > a |
Disclaimer div.footer > ul.links > li > a |
These are opportunities to improve the legibility of your content.
Internationalization and localization
If a page doesn't specify a `lang` attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. Learn more about the `lang` attribute.

These are opportunities to improve the interpretation of your content by users in different locales.
Names and labels
Informative elements should aim for short, descriptive alternate text. Decorative elements can be ignored with an empty alt attribute. Learn more about the `alt` attribute.

div.RootView > div.footer > p > img div.RootView > div.footer > p > img |
These are opportunities to improve the semantics of the controls in your application. This may enhance the experience for users of assistive technology, like a screen reader.
Best practices
Disabling zooming is problematic for users with low vision who rely on screen magnification to properly see the contents of a web page. Learn more about the viewport meta tag.

BForm Accessibility2 of 2 controls have issuesREVIEW
| Control | Type | Label | Method |
|---|---|---|---|
| identifier | text | (#room:example.com, @user:example.com) | placeholder only |
| input | submit | (none) | none |
Form controls need a <label>, aria-label, or aria-labelledby for screen readers.
<input type="submit">
Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.
Source: WCAG 2.1 SC 3.3.2
Placeholder text disappears on focus and is not a reliable label.
<input type="text" name="identifier">
Placeholder-only labels disappear when the user starts typing — they must remember what the field was for.
Learn more ▾ ▴
Placeholders are NOT labels. They vanish on input, fail color contrast checks (most are gray), and don't satisfy WCAG SC 3.3.2. Always use a real <label> alongside (or aria-labelledby).

Images without alt text are invisible to screen readers.
Each image without alt text is a WCAG 1.1.1 failure — invisible to screen-reader users, lost from Google Image Search.

WCAG 2.1 Level A requires text alternatives for non-decorative images. Empty alt='' is fine for decorative; meaningful images need descriptive text. Common fixes: CMS audit + bulk add, build-time linter (alt-text-required ESLint rule), CI gate on Lighthouse a11y score.

Links with target="_blank" without rel="noopener" leak the originating page's window context — security and UX issue.
Learn more ▾ ▴
Without rel="noopener", the new tab can navigate the original tab via window.opener (tab-nabbing attack). Modern browsers default to noopener for target=_blank but only since recent versions. Always set rel="noopener noreferrer" explicitly.

Methodology: The top 20 text elements by font size were checked. Background color was sampled from the desktop screenshot using a 5-point pattern. WCAG 2.1 AA requires 4.5:1 for normal text and 3:1 for large text.
