Implementing Header and Footer Banners on Jitsi Welcome page

Hi,

I’d like to implement some header and footer banners on my Jitsi setup. I was able to implement a header banner by adding a (div style=“desired settings”)(banner-text) to the body.html. How do I implement the footer-banner without affecting the header banner? Does the footer-banner go in the body.html or the index.html? How should the html code be formatted to keep it from interfering with the rest of the Jitsi main page setup?

Thanks
