Arrow bouncing to the bottom right corner in CSS - css

Question

I need an arrow to slightly move (bounce) to the bottom right corner on hover, using CSS. I've used the code below and I like what it does however this only moves the arrow left/right. How do I amend it so that it moves slightly to the bottom as well? I've tried using 'translateY' but couldn't workout the exact pixel amount for the animation to be smooth.
I've tried using 'bounce' but actually 'swing' seems to look better.
What I'm looking for is the kind on animation of this page:
http://ianlunn.github.io/Hover/ (called 'Wobble to Bottom Right')
.arrow:hover{
-webkit-animation: swing 1s ease;
animation: swing 1s ease;
-webkit-animation-iteration-count: 1;
animation-iteration-count: 1;
}
#-webkit-keyframes swing
{
15%
{
-webkit-transform: translateX(5px);
transform: translateX(5px);
}
30%
{
-webkit-transform: translateX(-5px);
transform: translateX(-5px);
}
50%
{
-webkit-transform: translateX(3px);
transform: translateX(3px);
}
65%
{
-webkit-transform: translateX(-3px);
transform: translateX(-3px);
}
80%
{
-webkit-transform: translateX(2px);
transform: translateX(2px);
}
100%
{
-webkit-transform: translateX(0);
transform: translateX(0);
}
}
#keyframes swing
{
15%
{
-webkit-transform: translateX(5px);
transform: translateX(5px);
}
30%
{
-webkit-transform: translateX(-5px);
transform: translateX(-5px);
}
50%
{
-webkit-transform: translateX(3px);
transform: translateX(3px);
}
65%
{
-webkit-transform: translateX(-3px);
transform: translateX(-3px);
}
80%
{
-webkit-transform: translateX(2px);
transform: translateX(2px);
}
100%
{
-webkit-transform: translateX(0);
transform: translateX(0);
}
}

Answer 1

You have to use translate(x,y) instead of translateX(x) for 2d transformation as #fen1x mentioned in the comment above
Try this:
#keyframes hvr-wobble-to-bottom-right {
16.65% {
-webkit-transform: translate(8px, 8px);
transform: translate(8px, 8px);
}
33.3% {
-webkit-transform: translate(-6px, -6px);
transform: translate(-6px, -6px);
}
49.95% {
-webkit-transform: translate(4px, 4px);
transform: translate(4px, 4px);
}
66.6% {
-webkit-transform: translate(-2px, -2px);
transform: translate(-2px, -2px);
}
83.25% {
-webkit-transform: translate(1px, 1px);
transform: translate(1px, 1px);
}
100% {
-webkit-transform: translate(0, 0);
transform: translate(0, 0);
}
}
