僅舉個粗糙的例子:
<div class="border"></div>
body {
background: #000;
}
.border {
position: relative;
margin: 50px auto;
width: 100px;
height: 100px;
background: #fff;
}
.border:after {
content: '';
position: absolute;
top: -3px;
right: -3px;
bottom: -3px;
left: -3px;
background-image:
linear-gradient(to bottom, #ff0, #ff0 50%, #000 0%),
linear-gradient(to bottom, #ff0, #ff0 50%, #000 0%),
linear-gradient(to right, #ff0, #ff0 50%, #000 0%),
linear-gradient(to right, #ff0, #ff0 50%, #000 0%);
background-position: 0 0, 100% 0, 0 0,0 100%;
background-repeat: repeat-y, repeat-y, repeat-x, repeat-x;
background-size: 2px 10px, 2px 10px, 10px 2px, 10px 2px;
animation: border 200ms linear infinite;
}
@keyframes border {
0% {
background-position: 0 0, 100% 0, 0 0,0 100%;
}
100% {
background-position: 0 -5px, 100% 5px, 5px 0,-5px 100%;
}
}
