      <h1>Button <small>Bootstrap Visual Test</small></h1>

      <button type="button" class="btn btn-primary" data-bs-toggle="button" aria-pressed="false" autocomplete="off">
        Single toggle
      </button>

      <p>For checkboxes and radio buttons, ensure that keyboard behavior is functioning correctly.</p>
      <p>Navigate to the checkboxes with the keyboard (generally, using <kbd>Tab</kbd> / <kbd><kbd>Shift</kbd> + <kbd>Tab</kbd></kbd>), and ensure that <kbd>Space</kbd> toggles the currently focused checkbox. Click on one of the checkboxes using the mouse, ensure that focus was correctly set on the actual checkbox, and that <kbd>Space</kbd> toggles the checkbox again.</p>

      <div class="btn-group" data-bs-toggle="buttons">
        <label class="btn btn-primary active">
          <input type="checkbox" checked autocomplete="off"> Checkbox 1 (pre-checked)
        </label>
        <label class="btn btn-primary">
          <input type="checkbox" autocomplete="off"> Checkbox 2
        </label>
        <label class="btn btn-primary">
          <input type="checkbox" autocomplete="off"> Checkbox 3
        </label>
      </div>

      <p>Navigate to the radio button group with the keyboard (generally, using <kbd>Tab</kbd> / <kbd><kbd>Shift</kbd> + <kbd>Tab</kbd></kbd>). If no radio button was initially set to be selected, the first/last radio button should receive focus (depending on whether you navigated "forward" to the group with <kbd>Tab</kbd> or "backwards" using <kbd><kbd>Shift</kbd> + <kbd>Tab</kbd></kbd>). If a radio button was already selected, navigating with the keyboard should set focus to that particular radio button. Only one radio button in a group should receive focus at any given time.  Ensure that the selected radio button can be changed by using the <kbd>←</kbd> and <kbd>→</kbd> arrow keys. Click on one of the radio buttons with the mouse,  ensure that focus was correctly set on the actual radio button, and that <kbd>←</kbd> and <kbd>→</kbd> change the selected radio button again.</p>
