About

Scrollspy has a few requirements to function properly:

  • It must be used on a Bootstrap nav component or list group.
  • Scrollspy requires position: relative; on the element you’re spying on, usually the <body>.
  • Anchors (<a>) are required and must point to an element with that id.

When successfully implemented, your nav or list group will update accordingly, moving the .active class from one item to the next based on their associated targets.
