+  <p>No matter the implementation method, scrollspy requires the use of <code>position: relative;</code> on the element you're spying on. In most cases this is the <code>&lt;body&gt;</code>. When scrollspying on elements other than the <code>&lt;body&gt;</code>, be sure to have a <code>height</code> set and <code>overflow-y: scroll;</code> applied.</p>
 
   <h3>Via data attributes</h3>
   <p>To easily add scrollspy behavior to your topbar navigation, add <code>data-spy="scroll"</code> to the element you want to spy on (most typically this would be the <code>&lt;body&gt;</code>). Then add the <code>data-target</code> attribute with the ID or class of the parent element of any Bootstrap <code>.nav</code> component.</p>
