There's not much you need to know. It supports nesting and offsetting.
The idea is, you start with a row and add columns with a certain span to that row.
Here's a simple example.
<div class="row">
<div class="col span6">span6</div>
<div class="col span6">span6</div>
</div>Here's how you'd use nesting.
<div class="row">
<div class="col span6">span6</div>
<div class="col span6">span6</div>
<div class="row">
<div class="col span4">span4</div>
<div class="col span4">span4</div>
<div class="col span4">span4</div>
</div>
</div>And last but not least the offset.
<div class="row">
<div class="col span6 offset6">span6</div>
</div>I bet you didn't see that coming, did ya?
