I'm trying to move the text up so it's slightly layered on top of the video. I was able to do it on desktop but I am having trouble with the mobile CSS. It'll move left or right but I can't get it to move up or down. This is the code I've been using:
@media screen and (max-width: 640px) {
#blockidhere {
position: absolute;
margin-top: -100px;
}
