<h2>Input Sizing</h2>
<p>You can quickly size labels and form controls within a Horizontal form by adding .form-group-lg or .form-group-sm to the div class="form-group" element:</p>
<form class="form-horizontal" role="form">
<div class="form-group form-group-lg">
<label class="col-sm-2 control-label" for="lg">form-group-lg</label>
<div class="col-sm-10">
<input class="form-control" type="text" id="lg">
</div>
</div>
<div class="form-group form-group-sm">
<label class="col-sm-2 control-label" for="sm">form-group-sm</label>
<div class="col-sm-10">
<input class="form-control" type="text" id="sm">
