如何从php文件中删除css文件导入？

Question

Here is a simple plugin. It use CSS code and importing it. The problem is that in the HTML file there are several external CSS files.

My goal is to compress them in one CSS file. Here's the code from the plugin, to my mind, it imports the CSS file.

I already copied the plugins CSS code and transferred it to main CSS file. But how to delete the code plugin so that it will never import its CSS file?

function addStylesAndScripts()
{
  wp_enqueue_style('zvr-font', 'https://fonts.googleapis.com/css?family=Open+Sans');
  wp_enqueue_style('zvr-style', trailingslashit(plugin_dir_url(__FILE__)) . 'assets/css/zvr-styles.css', array() , "1.0.3");
  wp_enqueue_script('zvr-script', trailingslashit(plugin_dir_url(__FILE__)) . 'assets/js/zvr-script.js', array(
    'jquery'
  ) , "1.0.3");
  $localize = array(
    'ajax_url' => admin_url('admin-ajax.php') ,
  );
  wp_localize_script('zvr-script', 'zvr_data', $localize);
}
}

Answer 1

You can dequeue those scripts, but you need to execute it after the plugin does it. For example, add this to your theme's functions.php

function dequeue_unneeded_css() {
   wp_dequeue_style( 'zvr-style' );
}
add_action( 'wp_enqueue_scripts', 'dequeue_unneeded_css', 99999 );
