<!-- Example  -->

			 track-height="'320'"
			 tracking-id="tracking.id"
			 track-duration="'300'" 
			 style='overflow: scroll;position:fixed; height:100vh;width:300px;' >
	<!-- ng-repeat -->
	<div ng-repeat="item in tracking.items"
			 style="height:300px;margin: 20px;width:300px;background-color:blue;color:white;text-align: center;">
				{{item }}
	</div>

Notice that the track-height of the item includes the margin as well (margin + height). ##Directive Attributes Directive attribute | Value type| Description ------------ | ------------- | ------------- **track-scroll** | "" | intiates directive **tracking-id** | "expression or 'string'" | index id of your array of items for ng-repeat **tracking-duration** | "expression or 'string'" | how long you want the animation to be **track-height**| "expression or 'string'" | make sure the height of the element is correct as the demo indicates (height:300px, margin:20px -> tracking-height="'320'") ##To Dos - Setup Grunt serve - Extract and rewrite scrollTo animation method - Add $window option - Add offset option - Add Tests
