Chrome browser has a feature. When the content is less than one page, the vertical scrollbar on the right cannot be displayed. But this caused me a problem:
When I click on the link, the content is less than one page. When there are more than one page of links, the scrollbar changes from non-display to display, which causes the same icon to have some displacement.
I think it is appropriate to display the vertical scrollbar. When the content is less than one page, the right scrollbar is Gray, unable to move
Looking for a solution
Try setting the css style overflow:scroll for the body
html{overflow-y:scroll;}
