Tips to make this work

Exclude from CSS minify

If you are using CSS minify you must exclude the same files from that option.

Excluding multiple files

Wildcards don't work here. Each exclusion must be added with a new line. For example:

$excluded_files[] = '/wp-content/plugins/plugin-name/filename1.css';
$excluded_files[] = '/wp-content/plugins/plugin-name/filename2.css';
$excluded_files[] = '/wp-content/plugins/plugin-name/filename3.css';

For wildcard exclusions, please check: Exclude all CSS files in a folder / directory from Load CSS Asynchronously

Remove query string

Remove any query string following the .css extension. For example, to exclude:

https://example.com/wp-content/themes/neutro/style.css?ver=1.2.5

use:

/wp-content/themes/neutro/style.css

Excluding externally hosted files

Use the filepath following the domain name to exclude files not hosted on your own domain. For example, to exclude:

https://cloud.typography.com/6907774/6146531/css/fonts.css

Use:

/6907774/6146531/css/fonts.css
