I've been meticulously following the Google PageSpeed guidelines in order to optimize the performance of my website.
Upon running an analysis, Google provides me with a score based on their set guidelines.
There's one particular guideline that is causing my score to remain low:
It says, "Eliminate render-blocking JavaScript and CSS in above-the-fold content."
Your page has 1 blocking CSS resource which is causing rendering delays.
I have made several attempts to resolve this issue.
This includes embedding essential CSS directly into the HTML for initial rendering, as well as attempting to load CSS through an inline script.
At the end of my HTML body, I inserted the following code:
(function (document) {
if(!document) return;
var stylesheet = document.createElement('link');
stylesheet.href = 'http://www.my-website.com/bundles/styles/125/core';
stylesheet.rel = 'stylesheet';
stylesheet.type = 'text/css';
var head = document.getElementsByTagName('head')[0];
head.appendChild(stylesheet);
})(document);
Despite these efforts, Google PageSpeed continues to flag this as a render-blocking issue.
Why is this happening and what steps can I take to address this problem?
