I searched on google.com for above issue to remove unused CSS from my Website Data. i get many results but they all are not provide satisfied solution to find unused CSS File. Anyone have best solutions for above issue?
It depends on how big the mess is, and how long it has been neglected. For a small sight I would just do it manually; If it is a large site you might need to write some scripts to parse all the pages to find classes and ids to match up to CSS declarations and pick up inline style attributes. I am not aware of any tool that would reliably do the kind of audit and re-organization you seem to be indicating you need.
