i have 3 divs in a bootstrap well
i want my btn-groups on the same line, the first on the left, the second in the center and the last one on the right

is it possible ?
i don't want to use an external CSS file 

```
<div class="well">
<div>
    Unit of time
    <div class="btn-group">
        <!-- button -->
        <!-- button -->
        <!-- button -->
    </div>
</div>

<div>
    Offset
    <div class="btn-group">
        <!-- button -->
        <!-- button -->
    </div>
</div>

<div>
    Dates padding
    <div class="btn-group">
        <!-- button -->
        <!-- button -->
    </div>
</div>

```
