Here is the code snippet I am working with. However, I cannot seem to find the span6 or any span class. Can you help me understand why?
<link href="~/Content/bootstrap.css" rel="stylesheet" />
<script src="~/Scripts/bootstrap.js"></script>
<div class="container">
<div class="row">
<div class="span6">
@Html.LabelFor(m => m.AppName)
@Html.TextBoxFor(m => m.AppName)
</div>
<div class="span6">
@Html.LabelFor(m => m.HarmonyTarget)
@Html.TextBoxFor(m => m.HarmonyTarget)
</div>
</div>
