Additional css: bd-imagelink with custom fade out animation code?

Hi Themler, I am trying to make an image fade permanently on my homepage. I know the element i need to edit which is:

   .bd-imagelink-16 {
  position: absolute;
  top: 39.765%;
  left: 13.987%;
  right: 24.866%;
  bottom: 34.717%;
  height: 824px;
  width: 1023px;
  animation-name: fadeOut2;
  animation-duration: 5000ms;
  animation-fill-mode: forwards;

}@-webkit-keyframes fadeOut2 {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}
@keyframes fadeOut2 {
  0% {
    opacity: 1;
  }
  100% {
    opacity: 0;
  }
}
.fadeOut2 {
  -webkit-animation-name: fadeOut2;
  animation-name: fadeOut2;
  -webkit-animation-fill-mode: forwards;
  animation-fill-mode: forwards;

Can you please tell me where in the css in themler i need to do this for it to override themler animations?
