I am facing a simple issue that I can't seem to solve. My goal is to have a gif as the background, showing flowers growing, with a campaign logo and a donation button overlay. However, there seems to be an issue with the background getting cut off at the bottom when in full screen mode. It appears fine on mobile screens but not on desktop. Any ideas on what might be causing this problem?
Here is the Campaign Page. Your help would be greatly appreciated! Thank you.
