Fenêtre modale

Bonjour à tous,
J'ai le contenu d'une fenêtre modale qui apparaît furtivement avant un loader.
Le loader n'y est pour rien, cela m'arrivait avant de le mettre.
Voici les CSS de la modale + de son contenu :

.oModal {
  position: fixed;
  z-index: 99999;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  background: 
rgba(0, 0, 0, 0.8);
  opacity:0;
  -webkit-transition: opacity 400ms ease-in;
  -moz-transition: opacity 400ms ease-in;
  transition: opacity 400ms ease-in;
  pointer-events: none;
  overflow-y: auto;
}


.oModal:target {
  opacity:1;
  pointer-events: auto;
}

.oModal:target > div {
  margin:5% auto;
  transition: all 0.4s ease-in-out;
  -moz-transition: all 0.4s ease-in-out;
  -webkit-transition: all 0.4s ease-in-out;
}

.oModal > div {
  max-width: 60%;
  position: relative;
  margin: 1% auto;
  padding: 8px 8px 8px 8px;
  border-radius: 5px;
  background: 
#FF8C00;;
  transition: all 0.4s ease-in-out;
  -moz-transition: all 0.4s ease-in-out;
  -webkit-transition: all 0.4s ease-in-out;
  overflow-y: auto;
}

.oModal > div h2 {
  margin:0;
}
@media only screen and (max-width: 768px) {
.oModal > div {
  max-width: 80%;
}
}
