Some attributes are added with the elements for the implementation of this feature. 
These are:

   The value of data-spy is scroll.
2. data-target This attribute is used to connect the navigation bar with the scrollable area. 
   It takes the value as the name of the ID or class of the navigation bar.
3. data-offset This attribute specifies the number of pixels to offset from the top when calculating the position of the scroll.
