设置按钮button边距与位置

## 按钮

``````````````
<button class="btn btn-success navbar-btn btn-sm" type="button" style="float:left">保存</button>
<button class="btn btn-success navbar-btn btn-sm" type="button" style="float:left">取消</button>
``````````````

## 设置左/右边距

`````````````````````````````````````````````

<button class="btn btn-success navbar-btn btn-sm" type="button" style="float:left,margin-right:10px;">保存</button>
<button class="btn btn-success navbar-btn btn-sm" type="button" style="float:left">取消</button>

<button class="btn btn-success navbar-btn btn-sm" type="button" style="float:left">保存</button>
<button class="btn btn-success navbar-btn btn-sm" type="button" style="float:left;margin-left:10px;">取消</button>
`````````````````````````````````````````````

margin-right:10px;设置由右边距
margin-left:10px;设置左边距
</div>

## 补习

margin-top:10px;设置顶部边距
width:45%;每个按钮占空间的百分比
</button> 控件后空格符
style="float:right"控件靠右
style="float:left"控件靠左
</div>

## 总结

主要用到style,好像CSS也可以用，有时间再学！
