You can add whatever animation effect you want using your css stylesheet. A fade-in effect for example:
.fade-in {
opacity: 1;
animation-name: fadeInOpacity;
animation-iteration-count: 1;
animation-timing-function: ease-in;
animation-duration: 2s;
}
@keyframes fadeInOpacity {
0% {
opacity: 0;
}
100% {
opacity: 1;
}
}
Then use it in your passage like this:
@@.fade-in;Your text@@
