Speed Up – Optimize CSS Delivery

Description

This small plugin (5 Kb) loads the stylesheets asynchronously and improve page load times.

The recommended use of this plugin is to load your vital stylesheets synchronously and non-vital CSS files asynchronously.
Non-vital CSS-files can be for example: fonts, icons, before the fold template-specific CSS, etc.

You can choose which files to load synchronously with a filter in your function.php, eg.:

// exclude main and child stylesheets from delivery optimization
function exclude_from_delivery_optimization($handle){
    return in_array($handle, array('main-stylesheet', 'child-stylesheet'));
}
add_filter('speed-up-optimize-css-delivery', 'exclude_from_delivery_optimization');

Note: this only works if your other plugins and theme add the CSS correctly.

Installation

1. Upload the complete speed-up-optimize-css-delivery folder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress

THIS PLUGIN IS THE BEST PLUGIN I’VE EVER SEEN IN WORDPRESS. I had page load speeds around 3 to 5 seconds, but after I installed and activated this plugin, it dropped to 1.5 seconds. I was like “Bruh, is this for real? I have been trying to speed up my page for days, and it took only 1 plugin? Woah.” I appreciate the work.

It Works

This is great plugin! By use this plugin is possible to get green level into Google Page Speed Insight without using any cache plugin. Off course javascripts have to be loaded asynchronously and (or) defer.
