Animation CSS3: display + opacity

Question

I have got a problem with a CSS3 animation.

.child {
    opacity: 0;
    display: none;

    -webkit-transition: opacity 0.5s ease-in-out;
    -moz-transit         


        

Answer 1

To have animation on both ways onHoverIn/Out I did this solution. Hope it will help to someone

@keyframes fadeOutFromBlock {
  0% {
    position: relative;
    opacity: 1;
    transform: translateX(0);
  }

  90% {
    position: relative;
    opacity: 0;
    transform: translateX(0);
  }

  100% {
    position: absolute;
    opacity: 0;
    transform: translateX(-999px);
  }
}

@keyframes fadeInFromNone {
  0% {
    position: absolute;
    opacity: 0;
    transform: translateX(-999px);
  }

  1% {
    position: relative;
    opacity: 0;
    transform: translateX(0);
  }

  100% {
    position: relative;
    opacity: 1;
    transform: translateX(0);
  }
}

.drafts-content {
  position: relative;
  opacity: 1;
  transform: translateX(0);
  animation: fadeInFromNone 1s ease-in;
  will-change: opacity, transform;

  &.hide-drafts {
    position: absolute;
    opacity: 0;
    transform: translateX(-999px);
    animation: fadeOutFromBlock 0.5s ease-out;
    will-change: opacity, transform;
  }
}
