The number immediately before -webkit-, -ms- or -moz- is the first browser version number that supports this prefix attribute.
Example:
@keyframes myfirst{
from {background: red;}
to {background: yellow;}}
@-webkit-keyframes myfirst /* Safari 与 Chrome */{
from {background: red;}
to {background: yellow;}}

p{
animation: myfirst 5s;
-webkit-animation: myfirst 5s; /* Safari 与 Chrome */}Note: You must define the duration of the animation The name and duration of the animation. If the duration is omitted, the animation will not run because the default value is 0.

background:red;
position:relative;
