## 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

Does what it says on the tin, which Google pagespeed likes a lot.

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.

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.
