8.头部/底部添加按钮

头部/底部可以添加按钮，按钮的样式根据头部/底部来设定，所以你不需要为按钮添加额外的样式。

  <button class="button icon ion-navicon"></button>
  <h1 class="title">Header Buttons</h1>
  <button class="button">Edit</button>
</div>



button-clear 类可以设置无背景和边框的头部/底部按钮。

<div class="bar bar-header">
  <button class="button button-icon icon ion-navicon"></button>
  <div class="h1 title">Header Buttons</div>
  <button class="button button-clear button-positive">Edit</button>
</div>



9.按钮栏

我们可以使用 button-bar 类来设置按钮栏。以下实例中，我们在头部和内容中添加了按钮栏。

<div class="button-bar">
  <a class="button">First</a>
  <a class="button">Second</a>
  <a class="button">Third</a>
</div>
