Jquery loading

public content distribution networks (CDNs) that host jQuery.

A CDN is a centralized distributed network of servers that deliver files to the user using the server that is closest to them. In our case Jquery libraries are also hosted by some of the gaints of CDN.

we can call jquery methods after document is ready. so we do as below...

$(document).ready(
        function () {
// actual code              

$("img:odd").mouseenter(function (e) { $(this).css("color", "red"); })
                    .mouseout(  function (e) { $(this).css("opacity", 1.0); });
                     });
