CSS解析顺序提高性能

Question

Would css parse quicker if it was in the order that its needed on page? If so what sort of difference would it make and are there any online tools that would sort it in order?

Answer 1

As others have said, as far as CSS parsing goes, I would assume this to be negligible. However, this is definitely true for HTML when loading JS or CSS . It becomes especially noticable when downloading from multiple CDNs.

If you are concerned and can host the site on either github.io or your own webpage, use Google Pagespeed Insights to benchmark performance on more basic things.
