PASS
1 of 4 controls have issues
Critical::
1 control(s) without accessible label
Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

Info::

Form controls need a <label>, aria-label, or aria-labelledby for screen readers.

<input type="submit" name="search_submit" id="edit-search-submit">

Why this matters

Form controls without labels — assistive tech announces 'edit text' with no context; users can't complete forms.

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.

ARIA

Focusable descendents within an `[aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers. Learn how `aria-hidden` affects focusable elements.

Why this matters

Informational: a Permissions-Policy directive showing feature -> allowed origins.

Source: MDN Permissions-Policy

Failing Elements
Search Submit Search div.l-header__row > div.l-header__menus > div.l-header__search > div.header-search-box
