Core Web Vitals: Show HTML Elements affecting Cumulative Layout Shift


I really appreciate that Cloudflare added the Core Web Vitals section under Browser Insights.

I was wondering if it’s possible to get the HTML Elements affecting Cumulative Layout Shift? I see that we can get different bits of information like URL, Browser, Operating System and Country, but I can’t find information about the HTML Elements actually causing the Cumulative Layout Shift.

If this is not currently supported, it would be extremely useful to have access to this information. Sometimes, CLS will only occur on some configurations, and it is very hard to reproduce the issue in a testing environment. Having access to HTML Elements causing the Cumulative Layout Shift would provide webmasters all the information they need to fix the issue on their websites.

Thank you.
