Customizing Login Page – Removing old css

Hey,

I am using the technique from
http://www.problogdesign.com/wordpress/custom-wordpress-login-screen/ to customize my login page. (code below)

While effective, it is really annoying that the old CSS file is not overwritten, so that the old CSS rules apply unless I explicitly do something else on top of them.

Firstly, am I doing something wrong?

Secondly, is there something I can add into my function that would allow the other CSS file to be overwritten or deleted? (I don’t want to do it manually because of doing it every time I upgrade…)

Cheers,

Ben

//Custom Login Code
function custom_login() {
echo ‘<link rel=”stylesheet” type=”text/css” href=”‘.get_bloginfo(‘template_directory’).’/custom-login/custom-login.css” />’;
}

add_action(‘login_head’, ‘custom_login’);
