Edited - I figured it out, I missed something incredibly simple.

This is failing every single test case. I honestly can’t figure out what is wrong with the first one, let alone any of the others.

Your code so far

<!-- file: index.html -->
<!DOCTYPE html>
<html lang="en">

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Confidential Email</title>

</head>

<body>
<main id="email">
  <div id="confidential">CONFIDENTIAL</div>
  <div id="top-secret">TOP SECRET</div>

  <p>This is a highly sensitive document. <span class="blurred">The target is moving</span> to the secondary location.</p>
  <p>Please ensure that <span class="blurred">Agent Smith</span> is notified immediately upon arrival.</p>
  <p>The password for the encrypted file is <span class="blurred">Alpha-99-Beta</span>. Do not share this.</p>
