<p><strong>Note:</strong> You can also add padding to the navigation bar, instead of each link. However, if you do this, note that the links do not get full padding on hover:</p>
<p>w3-padding-small:</p>
<div class="w3-bar w3-border w3-green w3-padding-small">
  <a href="#" class="w3-bar-item w3-button">首页</a>
  <a href="#" class="w3-bar-item w3-button">链接 1</a>
  <a href="#" class="w3-bar-item w3-button">链接 2</a>
</div>
<p>w3-padding:</p>
<div class="w3-bar w3-border w3-green w3-padding">
  <a href="#" class="w3-bar-item w3-button">首页</a>
  <a href="#" class="w3-bar-item w3-button">链接 1</a>
