CSS3动画 – 平滑无限循环

我制作了一个小背景动画,其中div随着时间的推移会改变颜色.
它工作顺利,但当它达到100％时,它会直接跳到0％而没有任何转换.
我在google上搜索并尝试了不同的动画制作方式,但是如果动画我一直无法获得流畅的“重启”.

我错过了什么？

-webkit-animation: pulsate 20s infinite;
animation: pulsate 20s infinite;
-moz-animation: pulsate 20s infinite;

            @-webkit-keyframes pulsate {
                0% {background: @black}
                25% {background: @red}
                50% {background: @blue}
                75% {background: @orange}
                100% {background: @green}
            }


            @keyframes pulsate {
                0% {background: @black}
                25% {background: @red}
                50% {background: @blue}
                75% {background: @orange}
                100% {background: @green}
            }

            @-moz-keyframes pulsate {
                0% {background: @black}
                25% {background: @red}
                50% {background: @blue}
                75% {background: @orange}
                100% {background: @green}
            }

解决方法

您只需要以另一种方式修复框架：使from(0％)和(100％)值相同：

html,body {   
    width: 100%; height: 100%;
    margin: 0;
    padding: 0;
}
body {
    -webkit-animation: pulsate 20s linear infinite;
    -moz-animation: pulsate 20s linear infinite;
    animation: pulsate 20s linear infinite;
}

@-webkit-keyframes pulsate {
    0% {background: black}
    20% {background: red}
    40% {background: blue}
    60% {background: orange}
    80% {background: green}
    100% {background: black}
}
@-moz-keyframes pulsate {
    0% {background: black}
    20% {background: red}
    40% {background: blue}
    60% {background: orange}
    80% {background: green}
    100% {background: black}
}
@keyframes pulsate {
    0% {background: black}
    20% {background: red}
    40% {background: blue}
    60% {background: orange}
    80% {background: green}
    100% {background: black}
}
