Answer

Cumulative layout shift (CLS) is how much content on the page moves about during the load.

layout shift score = impact fraction * distance fraction

You will see this type of error in PageSpeed Insights

Solution to reduce CLS:

Simply include width and height attributes in image tags.

<img src="banner.png" width="256" height="256" alt="verz banner" />

You can also specify your hight & width dimension on CSS.

img{ width: 100% height: auto; }

Note: Allow the browser to select what size each image is If you use srcset attribute to define images.

You can also use CSS property object-fit: contain for a feasible solution with no layout shift.
