Tribute Page Help- Responsive Section

Hi I need help making my tribute page responsive for the gradient section that I have on top of my plane background. I’m not sure what to do I tried adding media tag but it still doesn’t work.

I think you should set the .backpic-gradient to this:

.backpic-gradient {
	background: linear-gradient(rgba(0, 0, 0, 0) 0%, rgba(0, 0, 0, 1) 100%);
	position: absolute;
	margin-bottom: 0;
	height: 720px;
	width: 100%;
	top: 0;
}

Fix height and top: 0;

It worked! Thank you!
