Password protected page formatting

Hi, Can you please click on the button that says “Agent Login” towards the very bottom of my home page to see the following…the formatting of the password protected page needs a bit of fixing if possible. The password text box sits right on top of the submit button. I would like to have a space in between if possible. I would also like to change the color of the submit button to something else other then the light gray. I would also like to remove the comments area from that page. Thanks.
