I know there are a few questions on this but I was wondering where I can actually see the scripts that are blocking rendering.

Pagespeed Insights will provide a few scripts and CSS, but is there a more technical way to determine this? Waterfalls show request timing and have a duration for blocking, but it doesn't say what the culprit is.

Is there something in Chrome Developer Tools that can help here? I know the Element and Network tabs quite well but not sure if there's more features that can display these.

or I could be way off

Can anyone provide resources to where I can look into this further? I'm trying to relay info on how to diagnose the scripts and CSS that are blocking to a developer who has a complex technology stack.
