/* this animation not working */
#keyframes fromBottom
{
0%
{
opacity: 0;
transform: translateY(100px);
}
100%
{
opacity: 1;
transform: translateY(0);
}
}
.btn--animated
{
animation: fromBottom .5s ease-out;
}
I expect the button to move from bottom to its original position when page is loaded.

Try adding display: inline-block; to your .btn--animated and it'll work.
