Hi Ken,

Maybe you could try this technique / video / bookmarklet from the
Google PageSpeed Insights gang:
http://addyosmani.com/blog/detecting-critical-above-the-fold-css-with-paul-kinlan-video/

The idea here is to discover the above-fold, critical-path,
render-blocking CSS styles that keep a browser from well... painting
the page.

Best of luck!

Cheers,
- Eric

I want to select a portion of a web page (or of the html behind it), and be able to copy it ALONG WITH whatever CSS rules apply to that section of code. I don't want the whole 1000+ lines of css that pertain to the page, just the 5-10-100 rules that affect the styling of that section of the page.

It's so complex that it's hard to extract portions of a page for reuse. I want to take the top part of the page and re-write it in a simplified (ie, not 1000s of lines on non-relevant CSS) so I can re-purpose the same look-and-feel at the top of our customizable external services (discovery layer, etc.) I could laboriously reconstruct it, but I'm hoping that something exists to help.
