Question

I am building a wordpress site for a client but my client wants to have a different look of login screen, so my question is how can i change the look of default wordpress login form’s look. I don’t want to change any core files, is there any way to change the look of the login form without changing the core files.
Any kind of help will be highly appreciated, thanks!

Answer 1

You can do it without changing the core files, using the hook login_head, simply add these code inside your functions.php file and you are done

function custom_login_logo() {
    echo '<style type="text/css">
        h1 a { background-image:url('.get_bloginfo('template_directory').'/yourImageFolder/login_logo.png) !important; }
    </style>';
}
add_action('login_head', 'custom_login_logo');

Update: Also to change the link of the logo to the current site use following code snippet

function custom_login_url() {
    return get_bloginfo( 'siteurl' );
}
add_filter( 'login_headerurl', 'custom_login_url' );
