Hi! I have a really fun animation code I am using where there's a flying image across the screen as you scroll. Part of the code belongs in CSS, and another part belongs in the footer injection area (see below for both codes I'm using). I installed it and it worked perfectly. However, I realized that I just wanted this code to appear on the homepage only. So I added the collection ID to CSS. I was happy when I noticed this fixed this issue, until I scrolled down to the footer on all other pages and noticed the image sitting at the bottom of the footer. Any help?

// CSS CODE //

#collection-66e1f85031ff720c814003e3 {
.flier {
	pointer-events: none;
}
.flier > * {
/* Adjust animation duration to change the element’s speed */
        animation: fly 80s linear infinite;
        pointer-events: none !important;
	top: 0;
	left: 0;
	transform: translateX(-120%) translateY(-120%) rotateZ(0);
	position: fixed;
	animation-delay: 5s;
	z-index: 999999;
  }}

 /* Keyframe values control where the element will begin
    and end its trajectory across the screen. Each rule
    represents a path the element follows across the screen. */

@keyframes fly {

	98.001%, 0% {
                display: block;
		transform: translateX(-200%) translateY(100vh) rotateZ(0deg)
	}

	15% {
		transform: translateX(100vw) translateY(-100%) rotateZ(180deg)
	}

	15.001%, 18% {
		transform: translateX(100vw) translateY(-30%) rotateZ(0deg)
	}

	40% {
		transform: translateX(-200%) translateY(3vh) rotateZ(-180deg)
	}

	40.001%, 43% {
		transform: translateX(-200%) translateY(-100%) rotateZ(-180deg)
	}

	65% {
		transform: translateX(100vw) translateY(50vh) rotateZ(0deg)
	}

	65.001%, 68% {
		transform: translateX(20vw) translateY(-200%) rotateZ(180deg)
	}

	95% {
		transform: translateX(10vw) translateY(100vh) rotateZ(0deg)
	}
}
