css3动画不断变化

Question

我正在尝试实现css3动画....我打算在循环中不断改变我的动画影响,但问题是在一个循环之后它停止在红色它不会进一步改变它的颜色....如何继续循环...

在下面提供我的代码

div
{
width:100px;
height:100px;
background:red;
animation:myfirst 5s;
-moz-animation:myfirst 5s; /* Firefox */
-webkit-animation:myfirst 5s; /* Safari and Chrome */
-o-animation:myfirst 5s; /* Opera */
}

@keyframes myfirst
{
0%   {background:red;}
25%  {background:yellow;}
50%  {background:blue;}
100% {background:green;}
}

@-moz-keyframes myfirst /* Firefox */
{
0%   {background:red;}
25%  {background:yellow;}
50%  {background:blue;}
100% {background:green;}
}

@-webkit-keyframes myfirst /* Safari and Chrome */
{
0%   {background:red;}
25%  {background:yellow;}
50%  {background:blue;}
100% {background:green;}
}

@-o-keyframes myfirst /* Opera */
{
0%   {background:red;}
25%  {background:yellow;}
50%  {background:blue;}
100% {background:green;}
}

见这里:http://jsfiddle.net/9CZFS/1/

animation:myfirst 5s linear infinite;
                        ----^-----

您需要指定动画将永远循环.

此外,如果您希望动画流畅,则需要以相同的值开头和结尾:

0%,100%   {background:red;}
25%  {background:yellow;}
50%  {background:blue;}
75% {background:green;}
