Scroll to Top and Bottom

Every professional blogger should look after the decoration of their blog carefully so that visitors can navigate easily throughout the blog. If your blog have infinite page scroll or your post contains information, a lot, it would be very annoying for every reader to go back to the top of the page by either refreshing the page or dragging the scroll bar all the way back to the top. Jump to top (and bottom) is that's why very essential element for every blog decoration. But it would be far more stunning to scroll gradually instead of just jump to the top (which exactly Home button does). You can find this feature in almost every blog and website. This tutorial will show you how to add a modern and simple scroll button to your blog.


Before you make any changes, it's recommended to backup your blog template to avoid template crush if anything goes wrong.

Let's begin.
  1. Go to 'Blogger' dashboard.
  2. Click the drop-down arrow adjacent to 'Go to post list' icon and select 'Layout' form the drop-down menu list.
  3. Click on 'Add a Gadget'. A new window will appear that contains list of all available gadgets.
  4. Scroll down and click on 'HTML/Javascript' gadget or the '+' icon close to 'HTML/Javascript' gadget.
    Add HTML/Javascript widget
  5. Select one item from these following scrolling plugins, copy (Ctrl+C) the code and paste (Ctrl+V) it inside the content area of 'HTML/Javascript' widget. Leave the title empty.
  6. Every plugin contains two buttons; scroll to top and scroll to bottom. To disable one, find (Ctrl+F)
    var showtop = true,
      showbottom = true;
    in the provided code and disable whichever you want by making corresponding value false.
