Warning!

The following example can make your website less accessible!

<!-- (BAD) -->
<h1 role="button">heading button</h1>
<!-- (GOOD!) -->
<h1><button>heading button</button></h1>
<th 
   tabindex="0" 
   role="button" 
   aria-label="Sort column"
>Name</th>
<th>
  Name 
  <button aria-label=
           "Sort column">
     🔼🔽
  </button>
</th>
<body aria-hidden="true">

…content…

<div id="modal" aria-hidden="false">

…modal content…

</div>

…content…

</body>
