Thank you very much, for your prompt and detailed response. I made the change and it seems to have fixed the issue.
I did notice that the wordpress editor said that there was an error in line 185:
@keyframes fallPerspectiveCPNU { 0% { transform-style: preserve-3d; transform: translateZ(0px) translateY(0px) rotateX(0deg); opacity: 1; } 100% { transform-style: preserve-3d transform: translateZ(400px) translateY(300px) rotateX(-90deg); opacity: 0; } }
but I have no idea what the error could be or whether it is a thing I need to worry about at all. I left it alone, and everything looks the way I want it to look. “If it ain’t broke, don’t fix it”
