  <h2>Right-aligned Dropdown</h2>
  <p>Use the w3-right class to float the dropdown to the right, and use CSS to position the dropdown content (right:0 will make the dropdown menu go from right to left).</p>
  <div class="w3-dropdown-hover w3-right">
    <button class="w3-button w3-black">Dropdown</button>

  <div class="w3-clear"></div>
  
  <p>Note: Remember to clear floats if you use w3-right or w3-left. Remove the div class="w3-clear" to understand why.</p>
