Minify Css/js And Use Gzip

Hello,

Im checking the SEO Score of my eshop and I have some error on CSS:

How to fix - HTML Page Size Test
In order to resolve this problem you are advised to:
  • use gzip compression
  • move all CSS style rules into a single, external and minified CSS file
  • minify all JS files and,if possible, try combining them into a single external JS file
  • use CSS layouts

How can I fix these errors? Any help are welcome :)

Regarding gzip compression, please contact hosting administrator

CSS and JS files are combined into single files in CS-Cart out of the box

thank you..

Still received the same error! Please check that screenshot:

and I wonder If i use the http://csscompressor.com/Can I replace the compressed code and just replace the whole code in the specific css.file? Can that working normally? What alternative ways are exist here?

But what about minify JS ?
