Answer 1

For use Jquery plug-in (library) you need to import Jquery first.

The better way is import all scripts at the end of your HTML.

Take care of the order (Jquery first).

Example of Jquery import (online version).

For some reason you don't want import script at the end, don't forget :

$(document).ready(function(){//code});

Some plug-in need HTML to be loaded before use them. So the script begins to end.
