Allow filter for CDN absolute URL in CSS

[unclhos]

How can I use CDN for assets in CSS? Is it possible to filter the url without going in a modifying the urls by hand?

Hello!

For this, I have written a seperate plugin as an addon. Check it here: https://github.com/LQ2-apostrophe/minit-cdn

Do you mean having your pull CDN serve the minited CSS file?

You could

• hook minit-url-css
• get protocol and host from wp_upload_dir()
• replace them with CDN protocol and CDN host (maybe from a constant in wp-config)
• return it

@unclhos I would probably use the minit-content-css filter (not tested):

add_filter( 'minit-content-css', function( $css ) {
    return str_replace(
        '//example.com',
        '//cdn.example.com',
        $css
    );
} );
