I'm having trouble getting one of my bootstrap hero units to respond to an offset command:
<div class="col-xs-6-offset-3 col-md-6-offset-3 col-lg-6-offset-3">
<div class="center hero-unit">
<h1>text</h1>
</div>
</div>
It appears and has css applied to it, so I know Bootstrap is working. But it takes up the entire 12 grids across. How can I get it to only take up 6 and be centered?
