在我看来，您可以使用如下的股票自举环境来做到这一点:

In my opinion you can do this with a stock bootstrap environment like this:

<div class="row-fluid">
  <div class="span4 text-left"><a href="#" class="btn">Btn1</a></div>
  <div class="span4 text-center"><a href="#" class="btn">Btn2</a></div>
  <div class="span4 text-right"><a href="#" class="btn">Btn3</a></div>
</div>

这使得三个<div>的span4列构成了用于引导的十二列网格.

This makes three <div>'s that span4 columns that make up the twelve column grid for bootstrap.

您不需要添加任何额外的CSS，因为.text-left，right和center类随引导程序一起提供.

You don't need to add any extra CSS as those .text-left, right and center classes ship with bootstrap.
