CSS Absolute desde el centro y no en la esquina

this makes it so position absolute focuses in the middle of the element
instead of the top-left corner

.parent{
  position: relative;
}
.child-element-you-want-centered {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}
