<div class="w3-container">
<h2>导航栏尺寸</h2>
<p>添加 w3-small、w3-large、w3-xlarge 或 w3-xxlarge 以更改导航的大小（将更改每个链接的字体大小）。</p>

<p>w3-large:</p>
<div class="w3-bar w3-border w3-green w3-large">
  <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>
  <a href="#" class="w3-bar-item w3-button">链接 3</a>
</div>

<p>w3-xlarge:</p>
<div class="w3-bar w3-border w3-green w3-xlarge">
  <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>
  <a href="#" class="w3-bar-item w3-button">链接 3</a>
</div>

<p>w3-xxlarge:</p>
<div class="w3-bar w3-border w3-green w3-xxlarge">
  <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>
  <a href="#" class="w3-bar-item w3-button">链接 3</a>
</div>

<p>If you want more space between each link, instead of increasing the font-size, you could add a w3-padding-classes to each link:</p>
<div class="w3-bar w3-border w3-green">
  <a href="#" class="w3-bar-item w3-button w3-padding-16">首页</a>
  <a href="#" class="w3-bar-item w3-button w3-padding-16">链接 1</a>
  <a href="#" class="w3-bar-item w3-button w3-padding-16">链接 2</a>
  <a href="#" class="w3-bar-item w3-button w3-padding-16">链接 3</a>
</div>
