Executable PHP sidebar style not reading right

Hi,

I installed the Executable PHP widget and added the following code:

<h2>Login</h2>

<?php wp_register(); ?>

<?php wp_loginout(); ?>

I am using the Blixed-10 theme and for some reason, the php code that I added, doesn’t have the right style as the rest of the items on the sidebar. Any ideas how I can fix this?
