Many times you open a link, and thanks to the Progressive loading, you are able to read and interact with the fragments that your computer has already downloaded, instead of waiting for the whole page to load – but suddenly you find yourself back near the top of the page.
These are the page jumps, which typically happen when the website inserts an image or other content above the visible area, pushing down what’s on the screen. And the end result is that you lose your place, and have to find it again.
Google thinks it’s cracked this problem with tool called Scroll Anchoring, which is found in the newest version of Chrome.
“Similar to other features designed to protect our users from bad experiences, starting in version 56 Chrome prevents these unexpected page jumps with a new feature called scroll anchoring. This feature works by locking the scroll position on an on-screen element to keep our users in the same spot even as offscreen content continues to load.”
According to the Google, scroll anchoring prevents almost three jumps per page view.
