Hello,
i am receiving warnings from google webmaster, that my posts are producing high CLS values.
They name the featured-post-image as a cause, so i
– started an chrome inkognito window,
– used the sizes for an iPhone 5 and
– reduced the bandwidth to 10k
so get the layout shift visually presented.
I recorded this for you and me:
https://sinnstiften.biz/2021-02-16-CLS
in the video i can see 3 changes:
1. first the menu has 2 line, then both are combined into one
2. there seems to be an avatar-image in the upper left corner, which will be moved after a while
3. after all of these the post-image makes a shift up. (i think, this is what google measured)
How can this effect be reduced or eliminated?
You can run your own tests on https://sinnstiften.biz/flipchart-gestalten/
Thank you,
David
