What is the difference between "jquery.min.css" and "jquery.css"?

Question

It is a simple doubt.

What is the difference between

http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.css

and

http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.css

Anything wrong happen If i replace any of them with other, in a live site? if both were untouched(not edited previously)?

Answer 1

You can replace them interchangeably.

The regular one is meant for examination and (if necessary) editing. The minified version makes the file as small as possible by removing all the whitespace it can. This makes it load faster for users.

Answer 2

The min version is minified, compressed. Functionally they should be identical. The minified version is smaller and downloads faster and should be used in production, but is unreadable and therefore bad during development.
