Animate open/close event

You will be able to add CSS transitions on it, yes, but this is something you need to do it by yourself since my plugin’s functionality is supposed to remain minimal.

Navigate to this link: http://yourwebsite/wp-admin/plugin-editor.php?file=read-more-without-refresh-for-Wordpress/index.php

and replace:

$new_string = ‘<span style=”background-color: #fff;”>…………………………. “\n”;

with the code that contains effects too in its style part.
