I'm running DNN v.7.2.2 and when I analyze my website in Google PageSpeed, I get a recommendation that I should "

Eliminate render-blocking JavaScript and CSS in above-the-fold content".

The following scripts are listed:

jquery.min.js

jquery-migrate-1.2.1.min.js

jquery-ui.min.js

WebResource.axd?d=...

Plus 2 .js files that relate to a skin I purchased from the store.

The following css are listed:

/portals/_default/default.css

/desktopmodules/html/module.css

/portals/0/portal.css

Telerik.Web.UI.WebResource.axd?compress=...

Plus 7 .css files that relate to a skin I purchased from the store.

Is it possible to move the execution and loading of any of these scripts until after the page has loaded, or maybe load them asynchronously? Can anything be done with the css files?

I'm only getting a 78/100 score on

Google PageSpeed, and I really need to fix it. Any help will be greatly appreciated.
