标签有一个背景图片,我想把它无限缩放。我尝试在动画中改变
background-size
属性,但是你会发现,在动画过程中会有噪声或震动。如何去除这个问题?.pre-loader {
position: fixed;
left: 0px;
top: 0px;
width: 100%;
height: 100%;
z-index: 9999;
background: url('https://upload.wikimedia.org/wikipedia/commons/a/ab/Android_O_Preview_Logo.png') center no-repeat #fff;
background-size: 50%;
animation: loading 5s ease-in-out infinite;
}
@keyframes loading {
0% {
background-size: 50%
}
50% {
background-size: 55%
}
100% {
background-size: 50%
}
}
<div class="pre-loader"></div>
