@Nafees, I never suggest you to upload your any CSS using Google Drive because its server is very very slow. Reason- whenever it loads, firstly - googledrive.com redirect to drive.google.com then it redirect to googledrive.com then again it redirects to drive.google.com and at last- the scripts loads and this is the reason because of which scripts uploaded on Google Drive always load slowly. I had wish to recommend you Google Code but sadly, it is shutting down.
My second choice is Dropbox for uploading CSS but dropbox is not very fast but faster than Google Drive. So you can use it! or Buy your own hosting as @mohammad did (downloads.mybloggertricks.com).
Hope it help you!
