One of the reasons I love Genesis is all the great shortcodes that are already programmed in. I wrote an article about the Genesis shortcode back in 2012 that you could use to add a “Back to top” link to any long pages. Since that time, Genesis has started using HMTL5, and removed the #wrap div that used to make that back to top link work. But no worries, you can still create a back to top link by just using a link to #. So, create a link that looks like this instead:
<a href="#">Back to Top</a>
So simply add this item to the bottom of a long page, to your footer, or even to a footer menu as a custom link! I use it in the footer of this site if you want to give it a try.
