I install it on every site I build. Does the job well.

Good Except Can't Name Files (4567.css etc)

By dbareis on February 11, 2023

When saving CSS as external file, I'm disappointed that you can't name the css file, you can change the permalink and then a duplicate CSS file is created with the name but it is still not used by this plugin.

It is much better than Jetpack's version which is horrible.

I have now stopped using it as it also forces you to load the CSS where I needed to conditionally include it, I am now using a text editor, FTP, and wp_enqueue_style() in a child functions.php. Much easier (at least after working it out), the below code added before the html header started (not sure if that matters):

function CompanyHeaderAssets()
    //--- Main Company CSS ------------------------------------------------
    $CssDir  = 'https://instawpcom.b-cdn.net/wp-content/themes/oceanwp-child-theme-master/';
    $CssName = 'Company CSS for Dynamic Pages.css';
    wp_enqueue_style("CompanyCss4All", "{$CssDir}{$CssName}", '', time());

    //--- Main Company CSS 4 ADMINS ---------------------------------------
    if  (IsCompanyVolunteer())
        //--- Not displaying to visitors ------------------------------------
        $CssName = 'Company CSS for Image Gallery Metadata Tooltips (Volunteers Only).css';
        wp_enqueue_style("CompanyCss4StaffOnly4ImageMetadata", "{$CssDir}{$CssName}", '', time());
add_action( 'wp_enqueue_scripts', 'CompanyHeaderAssets' );

Повалил сайт

Отличный плагин. Действительно ускоряет сайт, но перед установкой делайте резервную копию, может конфликтовать с другими плагинами, но в целом достоит внимания. БД хорошо чистит от мусора.

Yes, that's what we need

This plugin is very effective. Thank you for this excellent work. One innovation I could wish for in the upcoming versions of the plugin would be to add HTML-elements to the <head> section. When we import CDNs or scripts such a feature would come in handy.

JS File read as HTML File

Einfach Genial

Sehr guttes un brauchbares Tool. Feines und ohne großen Aufwand zu Bedienen. Danke

Great plugin!

This plugin is excellent. The only thing missing is the ability to add functions to avoid having to enter the child theme (to edit functions.php).

Works ok, but...

By Lazylonewolf on February 11, 2022

I was hoping this can replace the Customizer's Custom CSS, but... My styling is working for the most part after completely erasing the Custom CSS and replacing it with this. However, my styling for the #header's @media screen and (max-width:980px) just doesn't work for some reason, yet it works in Customizer's Custom CSS. It keeps using the #header's default size. I dunno if this is an issue of cascade priority or not. As I'm not sure what CSS isn't working because of this plugin and I have no time to recheck everything, I guess I'll return to using the Customizer.
