Progressbar widget in jQuery

<!–
Well, you may have notice that i am including files like jquery-ui.min.js without using only jquery-ui.js and so on. This is why because i am using minified versions and why?
cause that the size of minified version is less then the normal version.

Lets do some animation using progressbar
