<span class="label label-danger">Tip</span><br>
Since <a href="http://bootsnipp.com">bootsnipp.com</a> uses frames, you have to<br>
open a new window in order for this to work - <a href="http://bootsnipp.com/iframe/82BW" target="_blank">view in new window <sup><span class="glyphicon glyphicon-new-window"></span></sup></a>
<br>
<strong>Reason:</strong><br> The w3.org validator links are coded to the referring URL. (you could hard code your URL if you wish)
