Library for tracking css

[Bogdaan]

Hi. First of all thanks for your work.
Your code inspired me to write small library for tracking css (i call it spycss).

You can see sources at https://github.com/Bogdaan/spycss
And small demo at https://github.com/Bogdaan/spycss-demo (live demo - https://spycss.hcbogdan.com)

I will be grateful if you will advise what can be improved.
