LCP entire body container and implications on lazy loading logic

[Tim Manalo]

Hello,

When our page loads, the entire container that holds above/below the fold content is considered the LCP element.

Below the fold I see visible images rendered that are supposed to be lazy loaded via HTML attributes and videos that are lazy loaded via JS (not HTML attribute preload="none").

If the browser/user device is considering the entire container for LCP, does that mean our lazy loading logic for both images/videos is overwritten based on our page's loading logic? I feel our page should be served to only consider the marquee's content above the fold as the LCP (ambient video image).

Please let me know your thoughts, I've never seen an entire page's body content be considered LCP before! Thank you for the time.


Best,
Tim

May you share a link to help us take a look?

(And if it takes more than just opening and loading, perhaps also specific instructions or even a trace which demonstrates an example, preferably shared via https://trace.cafe)
