Hi Jen,

Thanks for reaching out!

You can try setting the scroll position of the logo object to ‘Fixed’.

Please find more details‌ here: Prototype scroll and overflow behavior

For the banner, placing a banner object and images within a frame would be an option.

Here’s a reading that might be helpful:Groups vs. Frames

Also, I’ve made a sample file using the feature mentioned above. Feel free to import it and check it out.

Hope this helps! Let me know if I can assist with anything else.
