Nice tutorial on the Bootstrap3! I'm attempting to create a bootstrap3 implementation of a img-responsive type LOGO. I've added a class="row" with a 2 column layout - col-mid-3 and col-mid-9 above the ContentPane row per the demo. I've added the line to register the LOGO and I've added the following markup:
<div id="SiteHeaderLeft" runat="server" class="col-md-3">
<dnn:LOGO runat="server" id="dnnLOGO" />
<!--/Logo-->
<div id="SiteHeaderRight" runat="server" class="col-md-9">
