You just do it like:

```
@-webkit-keyframes autocomplete {
    0%   { opacity: 0.6; -webkit-transform: translate3d(0, 0, 0) scale(0.6); }
    100% { opacity: 1; -webkit-transform: translate3d(0, 0, 0) scale(1); }
}
@keyframes autocomplete {
    0%   { opacity: 0.6; transform: translate3d(0, 0, 0) scale(0.6); }
    100% { opacity: 1; transform: translate3d(0, 0, 0) scale(1); }
}
```
Where `autocomplete` is the name given to the keyframes, and does not require a prefix.
