title: Google Chrome download file with used CSS only
body: <p>Is it somehow possible to download a file with used CSS only after performing a page audit in Google Chrome? I'm using Bootstrap CSS and there's a lot stuff which is not used actually.</p>
  
  <p>The page audit shows me which CSS are used and which are not - but feature is pretty useless when dealing with a file with more than 10.000 rows if I can't download it somehow. So is there some convenient solution for that problem?</p>
