How can I ignore bottom property on mobile screens?
<div id="myID">...</div>
#myID {
  position: fixed;
  bottom: 5px;
  right: 5px;
  opacity: 1;
  cursor: pointer;
}
@media (min-width:305px) and (max-width:415px) {
  #myID {
    top: 8px !important;
    right: 225px !important;
    zoom: 0.6 !important;
    z-index: 99999999 !important;
  }
}
It tries to take bottom:5px and top:8px at the same time, and it causes some problems on mobile screens.
