                <h2>jQuery Validate: Custom CSS checkbox example</h2>

<p>This is an example of how jQuery Validate can be used to validate a custom CSS checkbox. The glow effect and tabbing doesn't work for natural reasons, but the error message is displayed as expected.</p>

<form id="fooForm" method="get" action="">
  <fieldset>
    <legend>Please provide some text and check the two checkboxes</legend>
    <p>
      <label>Text
        <input name="name" minlength="2" type="text" title="Please enter some text" required>
      </label>
    </p>
    <p>
      <label>Regular checkbox
        <input type="checkbox" name="cb" title="Please check this regular checkbox" required>
      </label>
    </p>
    <p>
      <label class="custom-checkbox">Custom checkbox
