Use the well as a simple effect on an element to give it an inset effect.
<?php
$well = new Barebone\Bootstrap\Well('Look, I\'m in a well!');
echo $well;
<div class="well">Look, I'm in a well!</div>
Control padding and rounded corners with two optional modifier classes.
<?php
$well = new Barebone\Bootstrap\Well('Look, I\'m in a large well!');
$well->large();
echo $well;
$well2 = new Barebone\Bootstrap\Well('Look, I\'m in a small well!');
$well2->small();
echo $well2;
<div class="well well-lg">Look, I'm in a large well!</div>
<div class="well well-sm">Look, I'm in a small well!</div>
