Bootstrap has 7 different types of buttons with contextual classes from which we can create buttons easily by using these classes (.btn-default, .btn-success, .btn-danger, .btn-primary, .btn-info, .btn-warning, .btn-link).

Bootstrap具有上下文类型的 7种不同类型的按钮 ，我们可以通过使用这些类轻松地创建按钮( .btn-default ， .btn-success ， .btn-danger ， .btn-primary ， .btn-info ， .btn-警告 ， .btn-link )。

Example Code:

示例代码：

<button type="button" class="btn btn-default">Button Default</button>
<button type="button" class="btn btn-primary">Button Primary</button>
<button type="button" class="btn btn-success">Button Success</button>
<button type="button" class="btn btn-info">Button Info</button>
<button type="button" class="btn btn-warning">Button Warning</button>
<button type="button" class="btn btn-danger">Button Danger</button>
<button type="button" class="btn btn-link">Button Link</button>

We can also make different size of buttons by using different button size classes (.btn-sm, .btn-lg, .btn-md, .btn-xs).

我们还可以通过使用不同的按钮大小类( .btn-sm ， .btn-lg ， .btn-md ， .btn-xs )来制作不同大小的按钮。

Example Code:

示例代码：

<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-default btn-md">Mediumbutton</button>
<button type="button" class="btn btn-success btn-sm">Small button </button>
<button type="button" class="btn btn-danger btn-xs">extraSmall button </button>

Here we also have a .btn-block level button spans the entire width of the parent element.

在这里，我们还有一个.btn块级按钮，它跨越父元素的整个宽度。

Example Code:

示例代码：

<button type="button" class="btn btn-primary btn-block">Button 1</button>
<button type="button" class="btn btn-danger btn-lgbtn-block">Button 2</button>

A button can be set to an .active class (appear pressed) or a .disabled class (unclickable) state.

可以将按钮设置为.active类(按显示)或.disabled类( 不可单击)状态。

Example Code:

示例代码：

<button type="button" class="btn btn-primary active">Active Primary</button>
<button type="button" class="btn btn-primary disabled">Disabled Primary</button>
