What is “WP Pro”?
See, you’re making so many assumptions here. One thing for sure, none of these come with a default WordPress installation. These are probably coming from some theme/plugin you’re using, and you’re assuming everyone would know your unique setup.
Kindly take your time to properly describe your WordPress site setup, including the specific plugin/theme that you need help with.
If you want help with CSS styling, we need to have a live link to a page showing the current situation, regardless of what theme or plugin you are using.
