You can achieve the desired effect even more elegantly using round by simply
omitting the middle keyframe value for z-index:
@keyframes orbit {
0% { margin-left: -150px; z-index: 10; }
50% { margin-left: 100px; }
100% { margin-left: -150px; z-index: 9; }
}
I'm sure it is possible to find some cases where floor more elegant. Likewise,
there will also be some where round is more elegant.
The main issue is that if we make CSS use floor it will be very hard to make
animations interchangeable between CSS and SVG (which is a Rec).
If you discover some really compelling reason for using floor then I'd
encourage posting it to public-fx.
