Trying to center buttons within a bootstrap 3 navbar. I've found some examples here, but they didn't seem to apply to (or work with) buttons. 

Here's my example...
<http://jsfiddle.net/jayinthebay/e3hj0kzw/>

I'm just trying to center BUTTON1, BUTTON2, BUTTON3 on the nav. 

I've tried:

```
text-align: center;

```

But I guess that's not it.
