Frank Geric: How large is "huge"?
Shao Chieh Lo: Frank Geric about 70, 000 characters every pages
Don Vermeer: Dont worry about it :)
Rob Watts: If you can externalise it do so, if you canâ€™t then itâ€™s not the end of the world either. You can look at top performing pages in competitive queries and find domains that have ranking documents full of inline css and theyâ€™re doing fine. The advantage is that through externalising a css file you can get it cached and so save on a bit of bandwidth for your users but the ranking benefits are negligible (in my humble op inion)
Stockbridge Truslow: Technically, in-line CSS is faster because there`s not a remote file call happening. We`re talking about a gigazillionth of a second though... the CSS needs to be loaded either way.
Ammon Johns: Only on the one-page (bounce) visit. Because external CSS is cached, and thus every subsequent page loads faster and leaner.
Shao Chieh Lo: So the majority time browser spend is in fetching not parsing? But also, the HTTP/2 can download external files in parrareel so external are not as harmful as before.

Factoring all these, inline is still better solutions?
Ammon Johns: Shao Chieh Lo I go with external for user-experience. Because one of the more important factors than speed is links and citations, and you don`t get worthwhile ones of either without impressing people.
Sam Mah: Yes, Inline CSS can increase the page file size. Therefore it can hurt the user experience. If you compress the code into one long line, this inline CSS doesn`t matter at all. To me, It`s all about the maintenance time. Would you like to change one page or 200 pages later?
Rienzi Mosqueda: Itâ€™s does affect loading speed. i clean it as soon as it gets on my radar.
