How do you find the cause of CLS?
You can find the elements that are causing CLS by submitting a URL to webvitals.dev/cls. This tool highlights elements on desktop and mobile that are causing CLS. Alternatively, you can open up Chrome's Developer Tools by left-clicking on a page and selecting (Inspect). From there, navigate to the Performance tab and click on the record button. As you browse the web, Chrome will now register any CLS and provide a breakdown of when it occurred at the end of the recording.
