axe-core rule: aria-command-name
Custom buttons, links, or menu items are missing accessible names
What it is
An element with role="button", role="link", or role="menuitem" has no accessible name, so assistive technology announces the role but not the purpose.
Who it blocks
Screen reader and voice-control users cannot identify or activate the control.
How to fix it
Add inner text, an aria-label, or aria-labelledby to the element carrying the role. Better: use a native button or a element, which handle most of this automatically.
Example fix
<!-- Before -->
<div role="button" class="close-x" onclick="closeModal()"></div>
<!-- After (better: use a real button) -->
<button type="button" class="close-x" aria-label="Close dialog" onclick="closeModal()"></button>
