Simple scroll to top example



Smooth scroll to top using jQuery




  • In this example, I used jQuery to implement the smooth scrolling effect.

  • For this, no plugin is used.

  • Tooltip visible after scrolling 50 pixels.

  • When user clicks on the below button, scroll to the top of a page (0 pixels).

  • It shows your "scroll to top" element(tooltip) only after the user has scrolled down the page 50 percent

  • 800 is delay. It is scroll duration. Can be set to any number as needed.
