Explanation: True or false? Cumulative Layout Shift is only measured on a page’s first load.


Explanation: False. Cumulative Layout Shift (CLS) is not exclusively measured on a page's first load. CLS is a metric that quantifies the visual stability of a web page by measuring the unexpected layout shifts that occur as the page loads and while the user interacts with it. These shifts can occur due to various factors such as images or ads loading asynchronously, font rendering changes, or dynamically injected content altering the layout. CLS is cumulative, meaning it accumulates all layout shifts that happen within the lifespan of the page visit. Therefore, it is not limited to just the initial page load but considers all changes to the layout that occur during the user's session on the page. By monitoring CLS over time, web developers and site owners can identify and address elements causing unexpected shifts, ultimately improving the user experience and reducing user frustration. Thus, the correct answer is False.
