By using the following code in your functions.php
file, I believe you can achieve the required result.
function login_stylesheets() {
wp_register_style( 'animate_css', 'https://cdnjs.cloudflare.com/ajax/libs/animate.css/4.1.1/animate.min.css' );
wp_register_style( 'my_login_stylesheet', get_template_directory_uri() . '/LINK/TO/YOUR/CSS/FILE.css' );
wp_enqueue_style( 'animate_css' );
wp_enqueue_style( 'my_login_stylesheet' );
}
add_action( 'login_head', 'login_stylesheets' );
The above wp_register_style
function is derived from the WordPress Codex. From here it is just a matter of editing the my_login_stylesheet
CSS file and customising to your hearts content! (Be sure to use this link for referencing login CSS classes. Also make sure to change /LINK/TO/YOUR/CSS/FILE.css
to the directory of your actual CSS file.)
I hope that answers your question!
