Is it feasible to utilize CSS keyframes animation on pseudo-elements like 'before' and 'after'? I'm creating a web service for mobile devices and I want to make an element blink without affecting the element itself. I've thought of two ways to achieve this: one is by covering the element with another element and animating that, and the other is by using a pseudo-element, but it doesn't seem to be effective.
CSS:
.fadeElement {
background-color: #000000;
width: 60px;
height: 60px;
}
.fadeElement:after {
display: block;
content: '';
position: relative;
height: 100%;
width: 100%;
z-index: 500;
background-color: rgba(249, 4, 0, 0.5);
animation-name: 'fade';
animation-duration: 2s;
animation-iteration-count: infinite;
-webkit-animation-name: 'fade';
-webkit-animation-duration: 2s;
-webkit-animation-iteration-count: infinite;
}
@keyframes 'fade' {
0% {
opacity: 0;
}
40% {
opacity: 0.5;
}
60% {
opacity: 0.5;
}
100% {
opacity: 0;
}
}
@-webkit-keyframes 'fade' {
0% {
opacity: 0;
}
40% {
opacity: 0.5;
}
60% {
opacity: 0.5;
}
100% {
opacity: 0;
}
}
HTML:
<div class="fadeElement"></div>
