我想动画滚动背景图像。我该如何将其设置为不断向上,而不是回来?尽管如此,它还是个混蛋。怎么可能?请帮助任何人知道。
我有一个链接:http://herinshah.com/wp/fortiflex/5-2/
CSS:
.et_pb_section.landing-page .et_pb_column_3_5 {
background-color: #f6eb00;
margin-right: 1%;
padding: 0 10px;
height: 100vh;
background-image: url(images/ragazzi-logo.png);
background-position: 0 0;
background-size: cover;
-webkit-animation: upward 15s linear infinite;
animation: upward 15s linear infinite;
border-right: 4px solid #000;
display: block;
background-repeat: repeat-y;
}
@-webkit-keyframes upward {
to {
background-position: 0 0;
}
from {
background-position: 0 2174px;
}
}
@keyframes upward {
to {
background-position: 0 0;
}
from {
background-position: 0 2174px;
}
}
您需要在div
内包装div
。这是相同的工作小提琴
html
<div class="main">
<div class="holder"></div>
</div>
CSS
*{
margin:0;
padding:0
}
.main {
height: 100vh;
overflow: hidden;
}
.holder {
height: 200vh;
-webkit-animation: upwards 2.5s linear infinite;
animation: upward 2.5s linear infinite;
background: url(http://herinshah.com/wp/fortiflex/wp-content/themes/Divi/images/ragazzi-logo.png) center yellow;
background-size: 100% 50%;
}
@-webkit-keyframes upward {
from {
background-position: 0% 0%;
}
to {
background-position: 0% -100%;
}
}
@keyframes upward {
from {
background-position: 0% 0%;
}
to {
background-position: 0% -100%;
}
}
我觉得自己不得不回答这个问题,因为我做了类似的事情:(双关语意图(和您的跳过动画正在给我癌症。
您需要弄乱伪:在元素之后,并正确获得高度。这应该让您入门。
您的图像也不完美地裁剪好,所以请修复它,您将很好地走。

我也看到您也在使用优雅的主题。&lt; 3 Divi Builder
我建议您有两个具有相同background
的div
标签。然后,对相同的div
进行动画播放,并使用divs
的定位和动画,以使其看起来不断滚动。
.container{
width:600px;
height:400px;
background-color:yellow;
margin:0 auto;
position:relative;
overflow:hidden;
}
.bg{
width:100%;
height:400px;
background-repeat:no-repeat;
background-size:contain;
position:absolute;
bottom:0;
}
.bg.bg1{
transform: translate(0,0);
animation: upward 3s linear infinite;
}
.bg.bg2{
transform: translate(0,100%);
animation: upward2 3s linear infinite;
}
@keyframes upward {
to {
transform: translate(0,-100%);
}
from {
transform: translate(0, 0);
}
}
@keyframes upward2 {
to {
transform: translate(0,0);
}
from {
transform: translate(0,100%);
}
}
这是我的方式。我的codepen。
