在构建一个加载器图标时,我注意到使用此动画,与Chrome相比,IE11中的行为异常:
@keyframes loader-2 {
0% {
transform: translateX(0);
}
50% {
transform: translateX(-1.6rem);
}
100% {
transform: translateX(0);
}
}
该元素首先正确地平移到侧面,但是在平移回移之前先移得很远。只能在IE11(在Chrome / Firefox中可以正常工作)上并且仅在伪元素(::after
)上如此操作。
有关示例,请参见this fiddle(或下面的代码片段)。顶部的点是span
,效果很好,底部的点是::after
元素,其行为很奇怪。
html {
font-size: 62.5%;
}
.splash {
align-items: center;
display: flex;
height: 100vh;
justify-content: center;
width: 100vw;
}
@keyframes loader-2 {
0% {
transform: translateX(0);
}
50% {
transform: translateX(-1.6rem);
}
100% {
transform: translateX(0);
}
}
.loader {
display: inline-block;
height: 3.2rem;
padding: 4rem 0;
position: relative;
width: 3.2rem;
border: 1px solid red;
}
.loader span {
animation: loader-2 1.5s ease infinite;
background: #024;
border-radius: 50%;
bottom: 0;
display: block;
height: 1.6rem;
left: 0;
margin: auto;
position: absolute;
right: 0;
top: 0;
width: 1.6rem;
}
.loader div::after {
animation: loader-2 1.5s ease infinite;
background: #024;
border-radius: 50%;
bottom: 0;
content: '';
display: block;
height: 1.6rem;
left: 0;
margin: auto;
position: absolute;
right: 0;
top: 3.2rem;
width: 1.6rem;
}
<div class="splash">
<div class="loader">
<span></span>
<div></div>
</div>
</div>
我当然可以不使用伪元素来解决此问题,但我仍然想知道是什么原因导致了此问题。

IE11不支持伪元素的动画和过渡,请在此处检查:

要变通解决此问题,您可以尝试为div使用ID并为其编写CSS,并避免使用伪代码。
修改后的代码:
html {
font-size: 62.5%;
}
.splash {
align-items: center;
display: flex;
height: 100vh;
justify-content: center;
width: 100vw;
}
@keyframes loader-2 {
0% {
transform: translateX(0);
}
50% {
transform: translateX(-1.6rem);
}
100% {
transform: translateX(0);
}
}
.loader {
display: inline-block;
height: 3.2rem;
padding: 4rem 0;
position: relative;
width: 3.2rem;
border: 1px solid red;
}
.loader span {
animation: loader-2 1.5s ease infinite;
background: #024;
border-radius: 50%;
bottom: 0;
display: block;
height: 1.6rem;
left: 0;
margin: auto;
position: absolute;
right: 0;
top: 0;
width: 1.6rem;
}
.loader #abc {
animation: loader-2 1.5s ease infinite;
background: #024;
border-radius: 50%;
bottom: 0;
content: '';
display: block;
height: 1.6rem;
left: 0;
margin: auto;
position: absolute;
right: 0;
top: 3.2rem;
width: 1.6rem;
}
<div class="splash">
<div class="loader">
<span></span>
<div id="abc"></div>
</div>
</div>
