Is combining CSS files still a good idea with HTTP/2?

Hi,
The GP cutomizer has an option to combine CSS files but I heard that it's not necessary with HTTP/2.
So do you recommend not using that option if the website supports HTTP/2?
Thanks
Hi there,
The Combine CSS does two things -
1. switches Unsemantic grid CSS for a light version
2. and combines it with 2 other CSS files.
Which results in 2 less requests and around 2kb less of page size.
So if there is any benefit to be seen with HTTP/2 it would probably be the smaller file sizes. Albeit very small.
On my lightweight sites where requests are below 30 and page size is below 200kb - that option has shown around a 0.1 second load time saving on HTTP/2.
On heavier sites any saving has been negligible.
Best way to tell is to test your site with and without the option enabled.
Ok I will give it a try then. Thanks :)
You're welcome - be nice to know if it improves for you :)
