我正在尝试创建一些闪烁的元素动画.它应该持续一秒半 - 它有红色边框和绿色BG,另外半秒绿色边框和红色BG.颜色的变化应该是即时的.
我试过这样的:
0, 49%, 99%, 100% {
background-color: rgb(117,209,63);
border: 3px solid #e50000;
}
49%, 50%, 99% {
background-color: #e50000;
border: 3px solid rgb(117,209,63);
}

它有点奏效,但颜色过渡非常缓慢.我也尝试了这个:
0%, 49% {
background-color: rgb(117,209,63);
border: 3px solid #e50000;
}
49%, 50% {
background-color: #e50000;
border: 3px solid rgb(117,209,63);
}
50%, 99% {
background-color: #e50000;
border: 3px solid rgb(117,209,63);
}
99%, 100% {
background-color: rgb(117,209,63);
border: 3px solid #e50000;

看看这个,对我来说,这个小提琴看起来非常准确:
.quadrat {
width: 50px;
height: 50px;
-webkit-animation: NAME-YOUR-ANIMATION 1s infinite; /* Safari 4+ */
-moz-animation: NAME-YOUR-ANIMATION 1s infinite; /* Fx 5+ */
-o-animation: NAME-YOUR-ANIMATION 1s infinite; /* Opera 12+ */
animation: NAME-YOUR-ANIMATION 1s infinite; /* IE 10+, Fx 29+ */
}
@-webkit-keyframes NAME-YOUR-ANIMATION {
0%, 49% {
background-color: rgb(117, 209, 63);
border: 3px solid #e50000;
}
50%, 100% {
background-color: #e50000;

很难猜出你想要的行为是什么,但很少有笔记:
animation-direction: alternate;.animation-timing-function: step-end(或者steps(1,end);你必须将你的"目标"状态移动到"中间"关键帧).cubic-bezier(.8,0,.2,1)或1,0,0,1- 在短时间内它与离散状态完全无法区分.p {
animation-duration: 2s;
animation-iteration-count: infinite;
animation-direction: alternate;
background-color: #75d13f;
border: .2em solid #e50000;
}
@keyframes anim {
to {
background-color: #e50000;
border-color: #75D13F;
border-right-width: 4.8em;
}
}
@keyframes anim-half {
50% {
background-color: #e50000;
border-color: #75D13F;
border-right-width: 4.8em;
}
}
