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

Hello,

I am using Google's PageSpeed to test my site.  I am getting a message:

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

Are there any clear and simple (browser caching for dummies kind of thing) so I can at least get started and understand.

The site is on an Apache (Linux) server and I have the expire and header modules running.  I am not running WordPress.

Please advise and thank you for your time.

Have a great day,

Don

Are you actually having a problem?  If you are not careful, Google's PageSpeed will make you crazy.  I don't think even they can make their own pages meet their 'standards'.

"render-blocking JavaScript" is like the tracking codes that Google and others use that contact another site.  I see them listed frequently in the lower left corner of the browser window while they are waiting to finish.  If you put them up higher in the page, then the part of the page after them has to wait for that code to finish before it is 'rendered'.

There is no "for dummies" on this.  You're dealing with the details of how the browser and the server interact.  The Google pages on the subject are probably your best guide.

Before you invest time in this, specifically what script/css file(s) is PSI telling you to fix?

There are certain things you may not want to fix. For example, often they'll include jquery or a css file that references font packages. If you were to load the site before these files, then you'd give the visitor a FOUT, which is actually a worse experience than the microsecond of load time being sacrificed.

I would enable PageSpeed and then sometimes the sites would have rendering issues.  As soon I disabled it, the rendering issue would go away.

Opted not to "fix" what Google says are issues.
