CLS
Abbreviation for Cumulative Layout Shift
In short and in plain language
CLS is a measure for a web page.
It shows how much the content moves around by surprise while the page loads.
A big search engine uses it to judge how easy a page is to use.
When text or buttons jump, people easily click the wrong thing. The page then looks restless.

CLS is a metric for how much the content of a page shifts unexpectedly while loading. It is one of the measures Google uses to assess the user experience of a page. Jumping text or buttons easily lead to accidental clicks and look unsettled.
