我想做成背景色来会变的那种，可是它不动，是哪里有问题？？代码如下
@keyframes move {
0%{
background-image:linear-gradient(to top left,red,orange,yellow,green,blue,indigo,violet);
}
15%{
background-image:linear-gradient(to top left,orange,yellow,green,blue,indigo,violet,red);
}
30%{
background-image:linear-gradient(to top left,yellow,green,blue,indigo,violet,red,orange);
}
45%{
background-image:linear-gradient(to top left,green,blue,indigo,violet,red,orange,yellow);
}
60%{
background-image:linear-gradient(to top left,blue,indigo,violet,red,orange,yellow,green);
}
75%{
background-image:linear-gradient(to top left,indigo,violet,red,orange,yellow,green,blue);
}
100%{
background-image:linear-gradient(to top left,violet,red,orange,yellow,green,blue,indigo);
}
}
div {
background-image:linear-gradient(to top left,red,orange,yellow,green,blue,indigo,violet);
width:300px;
