This module allows users to smoothly scroll back to the top of the page.

The link fades in on the bottom right-hand side of the content area, after the browser window has been scrolled beyond a certain point, and remains fixed during scrolling.

If users continues scrolling, the button nicely reduces its opacity to be less distracting during navigation.


    Note: The ideal place to add custom CSS in Oxygen is at Manage > Stylesheets in a new/existing Stylesheet.
