Change The WordPress Login Logo With A Simple Plugin (Advanced)

To change the WordPress login logo, you can create a simple plugin that uses the login_enqueue_scripts hook to add a custom CSS file to the login page. Here’s an example code:

1. Create a new folder in your WordPress plugins directory and name it something like “custom-login-logo”.
2. Create a new file in this folder and name it “custom-login-logo.php”.
3. Add the following code to the “custom-login-logo.php” file:

<?php
/**
 * Plugin Name: Custom Login Logo
 * Plugin URI: https://yourwebsite.com/
 * Description: Changes the WordPress login logo
 * Version: 1.0
 * Author: Your Name
 * Author URI: https://yourwebsite.com/
 */

function custom_login_logo() {
  // Replace "logo.png" with the name of your custom logo file
  $logo_url = plugin_dir_url( __FILE__ ) . 'logo.png';
  echo '<style type="text/css">
    #login h1 a {
      background-image: url(' . $logo_url . ');
      background-size: contain;
      width: 100%;
    }
  </style>';
}
add_action( 'login_enqueue_scripts', 'custom_login_logo' );

4. Save the file.
5. Create a new image file for your custom logo and save it in the plugin folder.
6. Activate the plugin in the WordPress admin panel.
7. Refresh the login page, and you should see your custom logo displayed instead of the default WordPress logo.

Note: Make sure that your custom logo file is in a suitable format and size for your needs.
