What are "Headers and Footers"?
The Headers and Footers link found in the Administration Area offers a more advanced way to customize your forum. You can use HTML, CSS, and JavaScript to help you customize different elements of your forum.
Any of the above mentioned coding entered into your Global Header / Footer will appear on every page of your forum. Moreover, customization codes added to the Main Header / Footer area will appear on your forum's main page, as well as select pages such as the Administration Area and member profiles. You can also add customization coding to specific boards if you choose.
If you don't have much coding experience, visit the Code Database on the ProBoards Support Forum for some great pre-made codes that are available for free.
