<ion-content padding class="page1">

  <h4>在按钮上添加block会使按钮取其父的宽度的100%。</h4>
  <button block>Block Button</button>
  <br />

  <h4>添加 full 按钮也将使按钮取其父的宽度为100%。但是，它也将删除按钮的左，右边框。当按钮应该在显示的整个宽度范围时，该样式是有用的</h4>
  <button full>Full Button</button>
  <br />

  <button small>最小</button>
  <button>默认</button>
  <button large>最大</button>
  <br />

  <button fab>圆形</button>

</ion-content>

/* --- page1.html ---*/

3、带有图标的 按钮

/* -- page1.html --*/

<ion-content padding class="page1">

  <!-- Float the icon left -->
  <button>
    <ion-icon name="home"></ion-icon>
    Left Icon
  </button>

  <!-- Float the icon right -->
  <button>
    Right Icon
    <ion-icon name="home"></ion-icon>
  </button>

  <!-- Only icon (no text) -->
  <button>
    <ion-icon name="home"></ion-icon>
  </button>

</ion-content>

/* -- page1.html --*/

4、在别的组件上使用 按钮

/* -- page1.html --*/

<ion-navbar>
  <ion-buttons start>
    <button>
      <ion-icon name="contact"></ion-icon>
    </button>
  </ion-buttons>

  <ion-buttons end>
    <button>
      <ion-icon name="search"></ion-icon>
    </button>
  </ion-buttons>
</ion-navbar>

<ion-list>

  <ion-item>
    Left Icon Button
    <button outline item-right>
      <ion-icon name="star"></ion-icon>
      Left Icon
    </button>

  </ion-item>
</ion-list>

<h4>虽然按钮可以自己使用，他们可以很容易地在其他组件中使用。例如，按钮可以添加到列表项或导航栏。</h4>

上图中 ion-buttons 一个 是 start 一个是 end 可以很好的控制他们的先后顺序
