Sample Script to Defer Loading Resources

deferResource.js

var delayStack = 100;

window.deferCSS = function (url) {

    var link = document.createElement('link');
    link.rel = 'stylesheet';
    link.href = url;

    link.type = 'text/css';

    delayStack += 10;

    window.setTimeout(function () {

        document.getElementsByTagName("head")[0].appendChild(link);
    }, delayStack);
};

window.deferCss = window.deferCSS; // prevent my forgetfulness

window.deferScript = function (url, delay) {

    var script = document.createElement('script');
    script.src = url;
    script.type = "text/javascript";
    delayStack += 10;

    window.setTimeout(function () {

        document.getElementsByTagName("head")[0].appendChild(script);
    }, delay == null ? delayStack : delay);

};
