How can I add HTML banner to the top of all pages?

[x-cart]

Hi,

I am using Confluence on Demand and would like to know how can I add any HTML code to the header of footer on all pages. I found the Documentation theme confguration section with the header/footer messages, but they do not allow me to put HTML text.

What can I do now?

Any help is appreciated!

Thank you.

In addition to what Jamie said, it is not possible due to restricted function in OnDemand.

I doubt you can put HTML anywhere, the reason being that they're trying to prevent again you using javascript for a XSRF attack or similar. Not quite sure why that applies to administrators, but I believe that's the reason.
