我在页面底部添加了jQuery.但是,当我在pagespeed见解(移动)上运行我的网站时,我收到错误：

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 2 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.

见：http://learnyourbubble.com和https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Flearnyourbubble.com&tab=mobile

但是,jQuery添加在页面底部.所以它应该低于一点.

如何删除此错误？
