Answer 1

may be you have syntax error somewhere in your css.

You can copy whole merged css and validate your css in css validator and check which line causing the issue. because in css after error the rest of the css code wont work so validate your css .

You can use below listed css validator

Or you can google it css validator and vaidate your css.
