// This below code is designed to handle the proper handling of in-page
// anchor offsets.  Specifically, it handles only those in-page anchors which
// have both an href and id attribute to correct for the issue of the a fixed
// bootstrap navbar header which by default causes in-page anchor offsets to
// be obscured by the top navbar.

// This Javascript solution is not as preferable as the pure CSS solution, so
// the pure CSS solution is used for those anchors which have no href
// attribute.
