axe-core rule: button-name
Buttons have no accessible name
What it is
One or more buttons contain no text that assistive technology can announce, typically icon-only buttons such as a hamburger menu, close button, or search button.
Who it blocks
Screen reader users hear only "button" and cannot tell what it does. Voice-control users cannot say a name to press it. Unnamed buttons frequently gate navigation menus and modal dialogs, blocking the whole site.
How to fix it
Add visible text, or an aria-label, to every button. Hide decorative icons inside the button from assistive technology with aria-hidden="true".
Example fix
<!-- Before -->
<button class="menu-toggle"><span class="icon-burger"></span></button>
<!-- After -->
<button class="menu-toggle" aria-label="Open navigation menu">
<span class="icon-burger" aria-hidden="true"></span>
</button>
