Hi Private,
To use custom CSS in the login page, simply add the following code snippet to your website:
/**
* Use custom CSS in the login page
*/
add_action( 'login_head', function() {
?>
<style>
/* Write your CSS code here */
</style>
<?php
}, 99 );
To add this code snippet to your site, we recommend that you use the Code Snippets plugin (https://wordpress.org/plugins/code-snippets/). If you have never activated this plugin, please read the following post: Adding Custom PHP Without Changing Your Child Theme.
Please also note that we don’t provide any theme customization. So, you shouldn’t expect other snippets from us unless it’s to fix an issue stemming from our own codebase. We always try our best to help theme users whenever we can and only provide code snippets out of courtesy to prevent them from waiting for the next update.
Regards,
