Position-Scrolling Attribute

While exploring this angularJS app example (), I came across an attribute named scroll-position in the following div tag that is set to "scrolled":

<div class="page-top clearfix" scroll-position="scrolled" max- 
height="50" ng-class="{'scrolled': scrolled}">

It might be a trivial question, but I can't seem to understand the purpose of this attribute and where it originated from.

The complete snippet is provided below:

<div class="page-top clearfix" scroll-position="scrolled" max-height="50" ng-class="{'scrolled': scrolled}">
  <a href="#/dashboard" class="al-logo clearfix"><span>Blur</span>Admin</a>
  <a href class="collapse-menu-link ion-navicon" ba-sidebar-toggle-menu></a>

  <div class="search">
    <i class="ion-ios-search-strong" ng-click="startSearch()"></i>
    <input id="searchInput" type="text" placeholder="Search for...">
  </div>

  <div class="user-profile clearfix">
    <div class="al-user-profile" uib-dropdown>
      <a uib-dropdown-toggle class="profile-toggle-link">
        <img ng-src="{{::( 'Nasta' | profilePicture )}}">
      </a>
      <ul  class="top-dropdown-menu profile-dropdown" uib-dropdown-menu>
        <li><i class="dropdown-arr"></i></li>
        <li><a href="#/profile"><i class="fa fa-user"></i>Profile</a></li>
        <li><a href><i class="fa fa-cog"></i>Settings</a></li>
        <li><a href class="signout"><i class="fa fa-power-off"></i>Sign out</a></li>
      </ul>
    </div>
    <msg-center></msg-center>
  </div>
</div>

When working with angular, using scroll-position="scrolled" is an attribute directive specific to angular. This directive has its own isolated scope that is local to the directive itself. It allows you to execute specified functions within the directive. In addition to this, there are other built-in directives such as ng-model, ng-value, ng-class, and more.
