是否可以为我的所有三个div使用一种样式,使其简洁明了,并保持动画的有效性?非常感谢任何帮助。

你的意思是将css应用于所有三个元素吗?如果是这样,你只需要这样做:
.a, .b, .c {
width: 15px;
height: 15px;
background: #dbdbdb;
border-radius: 50px;
display: inline-block;
}
.a {animation-delay: 1s;
animation: fade 1s forwards;}
.b {animation-delay: 2s;
animation: fade 2s forwards;}
.c {animation-delay: 3s;
animation: fade 3s forwards;}
@keyframes fade {
0% {opacity:0;}
50% {opacity:1;}
100% {opacity:0;}}

可能是这样的jsFiddle:
.a {
animation-delay: 1s;
animation: fade 1s forwards;}
.b {
animation-delay: 2s;
animation: fade 2s forwards;}
.c {
animation-delay: 3s;
animation: fade 3s forwards;}
.d{
width: 15px;
height: 15px;
background: #dbdbdb;
border-radius: 50px;
display: inline-block;}
@keyframes fade {
0% {opacity:0;}
50% {opacity:1;}
100% {opacity:0;}}
然后你的HTML看起来像这样:
<div class="a d"></div>
<div class="b d"></div>
<div class="c d"></div>

我对此表示怀疑,因为你的动画属性都不同,所以他们需要不同的类。但你可以通过在他们自己的类中保留所有常见属性来缩短你的CSS,如下所示:
.x {
width: 15px;
height: 15px;
background: #dbdbdb;
border-radius: 50px;
display: inline-block;
}
.a {
animation-delay: 1s;
animation: fade 1s forwards;
}
.b {
animation-delay: 2s;
animation: fade 2s forwards;
}
.c {
animation-delay: 3s;
animation: fade 3s forwards;
}
@keyframes fade {
0% {opacity:0;}
50% {opacity:1;}
100% {opacity:0;}}
像这样使用:
<div class="x a"></div>
<div class="x b"></div>
<div class="x c"></div>
