Bootstrap Video Modal - css

Question

Using Bootstrap for some video launching with Modal and I keep getting a weird offset video at the end of my webpage and when I click on the anchor tag it brings me to a dead link. I built a jsfiddle to even show my work. I only replaced the image and video, but I got the images from off line so its basically mimicking my code.
HTML:
<a data-toggle="modal" href="#videoModal">
<img class="img-responsive img-rounded" src="http://iconshots.com/wp-content/uploads/2010/01/final1.jpg">
</a>
<div class="modal fade" id="videoModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Learn how to make this app!</h4>
</div>
<div class="modal-body">
<iframe width="500" height="281" src="http://youtu.be/GWPc6EDwv8k" frameborder="0"></iframe>

Are you sure you have included all required JS libraries such as jQuery and Bootstrap.js
I have copied your code to Codepen and it works perfectly for me (click on the gears near CSS and JS titles to see included libraries)
Codepen example
<a data-toggle="modal" href="#videoModal">
<img class="img-responsive img-rounded" src="http://iconshots.com/wp-content/uploads/2010/01/final1.jpg">
</a>
<div class="modal fade" id="videoModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Learn how to make this app!</h4>
</div>
<div class="modal-body">
<iframe width="560" height="315" src="http://www.youtube.com/embed/KueEWP91tWc" frameborder="0" allowfullscreen></iframe>
