作为一名学生,我实际上正在制作自己的作品集。 对于标题,我尝试创建天空效果,图像水平滚动。我使用CSS和关键帧,我的问题是当图像结束时,它“重置”并且不会继续平滑滚动。 有没有办法让它“无限期地”继续下去? (我把持续时间改为5秒只是为了不让你等到40秒:p)
@keyframes animatedBackground {
from { background-position: 0 0; }
to { background-position: 100% 0; }
}
#header-top {
height: 190px;
background-image: url('http://image.noelshack.com/fichiers/2016/46/1479595480-clouds.png');
background-repeat: repeat-x;
animation: animatedBackground 5s linear infinite;
line-height: 400px;
}
<div id="header-top">
</div>
答案 0 :(得分:8)
我刚刚剪裁了你的图像,所以最后的一行与开始一致。然后,我将animatedBackground关键帧修改为在图像的另一端结束。
工作原理
@keyframes animatedBackground {
from {
left: 0px;
}
90% {
left: -562px;
}
100%{left: 0px;}
}
#header-top {
height: 190px;
width: 562px;
overflow-x: auto;
overflow-y: hidden;
}
* {
margin: 0;
padding: 0;
font-family:sans-serif;
}
.inner-cont {
width: 1126px;
position: relative;
animation: animatedBackground 4s linear infinite;
}
img{
border-right:1px solid black;
box-sizing:border-box;
}
&#13;
<div id="header-top">
<div class='inner-cont'>
<img src="https://archive.org/download/clouds-tiled/clouds-tiled.png" /><img src="https://archive.org/download/clouds-tiled/clouds-tiled.png" />
</div>
</div>
<h3>^ How it actually works(almost) ^</h3>
<h4>The spinback doesn't actually get animated, but it happens <br/>(The line separates the looped images from each other)</h4>

最终结果
@keyframes animatedBackground {
from { background-position: 0px 0; }
to { background-position: -562px 0; }
}
#header-top {
height: 190px;
width:100%;
background-image: url('https://archive.org/download/clouds-tiled/clouds-tiled.png');
background-repeat: repeat-x;
animation: animatedBackground 2s linear infinite;
line-height: 400px;
}
