On Hover Effect Not Working - html

Question

I am trying to implement a vertical wobble effect on my anchor tag, an example can be found here:
http://ianlunn.github.io/Hover/
I have this is my mark up:
.hvr-wobble-vertical {
display: inline-block;
vertical-align: middle;
-webkit-transform: translateZ(0);
transform: translateZ(0);
box-shadow: 0 0 1px rgba(0, 0, 0, 0);
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
-moz-osx-font-smoothing: grayscale;
}
<div class="col-lg-2 col-md-4 col-sm-6">
<div class="pin">
<a href="#" class="hvr-wobble-vertical">
<img src="http://cssdeck.com/uploads/media/items/2/2v3VhAp.png"/></a>
<p style="text-align: center;">
some clever text.
</p>
</div>
</div>
I am currently getting no result... Can someone give me some pointers of what I may be missing?

You're missing the animation keyframes :)
.hvr-wobble-vertical {
display: inline-block;
vertical-align: middle;
-webkit-transform: translateZ(0);
transform: translateZ(0);
box-shadow: 0 0 1px rgba(0, 0, 0, 0);
-webkit-backface-visibility: hidden;
backface-visibility: hidden;
-moz-osx-font-smoothing: grayscale;
}
.hvr-wobble-vertical:hover,
.hvr-wobble-vertical:focus,
.hvr-wobble-vertical:active {
-webkit-animation-name: hvr-wobble-vertical;
animation-name: hvr-wobble-vertical;
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-timing-function: ease-in-out;
animation-timing-function: ease-in-out;
-webkit-animation-iteration-count: 1;
animation-iteration-count: 1;
}
/* Wobble Vertical */
#-webkit-keyframes hvr-wobble-vertical {
16.65% {
-webkit-transform: translateY(8px);
transform: translateY(8px);
