Eliminate Render-Blocking Javascript And Css In Above-The-Fold Content


Does anyone know hot to fix this one please:

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

Your page has 1 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:[list]



Optimize CSS Delivery of the following:[list]



This is found on the Google webmaster tool to make the website speed, I have no idea what this and how to fix, I will very appreciate for your help.

Thank in advance!
