Smoothly scroll up the page with Drupal: Comparison of the modules "Scroll to Top" and "Back to Top"

In this short tutorial we look at two modules that have very similar functionality. We first look at the Drupal 7 Scroll to Top module and see how it can be used to create a nice button that scrolls to the top of the page. We then look at the Drupal 7 Back to Top module to see how it differs. These modules offer the same function but they have different settings/configuration options that make them unique.
