Sometimes, when there is too much content on the page, and when scrolling down, you have to go back to the header of the site, and you can flip the laziness up yourself you can implement button "Up" on jQuery.
At the end of the page, before closing the tag "</body>" set our button wrapper.
Next, you need to write the script itself for the appearance / hiding of the button when scrolling. We do this through jQuery, for this a library must be enabled.
Well and in the conclusion we register styles for the button. I will give an example that is implemented on the site.
