## Why is this an issue?

Even if all browsers are fault-tolerant, HTML tags should be closed to prevent any unexpected behavior.

### Noncompliant code example

    <html>
      <head>
        <title>Test Page    <!-- Noncompliant; title not closed -->
      <!-- Noncompliant; head not closed -->
      <body>
        <em>Emphasized Text  <!-- Noncompliant; em not closed -->
      <!-- Noncompliant; body not closed -->
    </html>

### Compliant solution

    <html>
      <head>
        <title>Test Page</title>
      </head>
      <body>
        <em>Emphasized Text</em>
      </body>
    </html>
