Boost website performance with Google Page Speed by optimizing CSS above the fold using this innovative Bootstrap Template Plugin

My Google PageSpeed Insights report suggests that I should place my CSS below the fold.

However, Bootstrap is being used as my templating plugin.

I am contemplating printing bootstrap.min.css inline on my homepage, but I hesitate because it may lead to inefficiencies in the overall site experience.

The option of using async or defer modifiers crossed my mind, but incorporating them might result in bootstrap loading incorrectly before fixing itself.

In order to enhance user experience, loading a CSS file once and caching it in the user's browser seems like a more sensible approach instead of having to load large plugins every time they visit a page.

This situation presents a conflict - Google aims for fast initial page loads, while inline styling information is not recommended for sustained site sessions.

Is there a solution to this dilemma that will ensure normal loading of my bootstrap site and at the same time improve my PageSpeed score?

Answer №1

Give this a try to see if it boosts your Google PageSpeed:

<script>
var loadCSS = function() {
var stylesheet = document.createElement('link');
stylesheet.rel = 'stylesheet';
stylesheet.href = 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css';
var head = document.getElementsByTagName('head')[0];
head.parentNode.insertBefore(stylesheet, head);
};
var requestFrame = requestAnimationFrame || mozRequestAnimationFrame ||
webkitRequestAnimationFrame || msRequestAnimationFrame;
if (requestFrame) requestFrame(loadCSS);
else window.addEventListener('load', loadCSS);
</script>
