Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 11 blocking script resources and 20 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:

Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

57.3KiB of the HTML response was required to render the above-the-fold content. This requires 3 network round-trips. Prioritize the above-the-fold content so that it can be rendered with only the first 2 round-trips' worth of HTML.

  • Only about 43% of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.

The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.

The page content is 417 CSS pixels wide, but the viewport is only 412 CSS pixels wide. The following elements fall outside the viewport:
