I ran a google page speed test and the following information was shown
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 1 blocking script resources. This causes a delay in rendering your page.
Approximately 54% 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.
