Rapid includes several built-in slots for adding content to the footer of your website.
The central footer content slot is intended for important campaign information, such as a declaration of how your website was funded.
![Example footer content, positioned in the center of the footer](https://assets-global.website-files.com/5da092a22e90ec1538d0e09b/5ddde0cc7f261530acf42124_footer_slot_2.png)
To customize this slot, enter your message in the 'Subheadline' textbox on the 'Site settings > Basic' screen of the NationBuilder Control Panel.
This content will appear in a floating box that is horizontally centered on desktop and vertically centered on mobile.
