Customizing the Password Reset Page

Customizing the Password Reset Page

I am trying to add custom verbage to the password reset page. I have modified the html document and entered some pretty basic html commands. However, all content is displayed, inlcuding my html tags. What am I missing?
 
Also the format which the text is displayed is different when someone signs in to reset their password versus when someone just clicks the reset password and answers the security questsions. Why is this?
