css - How to get a responsive button in bootstrap 3

I am using bootstrap 3 and I have the following html:

<div class="col-sm-2" >
    <a id="new-board-btn" class="btn btn-success" >Create New Board</a>
</div>

On a small screen, the text "Create New Board" is too long to fit on the button. I would like the text to wrap on to another line and the height of the button to increase to fit the text. Any tips on how to do this?

In Bootstrap, the .btn class has a white-space: nowrap; property, making it so that the button text won't wrap. So, after setting that to normal, and giving the button a width, the text should wrap to the next line if the text would exceed the set width.

#new-board-btn {
    white-space: normal;
}
