css compression question

Hi,

I've enabled css compression but the the browser still loads some css files separately.
Is this normal?
Please find the attachment.

Hi,
yes those files are not compressed to avoid problems on mobile devices and old IE browsers.

p.s.
Sure you can try to use alternative solution, for example plugin JCH Optimize - but you have to check on all devices if everything is okey before you will leave this high compression on.

Hi Pawel,

Thank you for the explanation.
