我找到了这个有趣的Codepen,我正在尝试进行2次风暴,向左风暴之一向右风暴。我试图复制背景ID并将其设置为类,但没有用。如果有人可以帮助,那就太好了! ps我是编码新手。
谢谢

:after
和:before
伪元素不能用于以下用途 相同的div / id / class / etc。
根据您的情况,您可以使用cloud class
复制风暴。
.cloud1:before {
position: absolute;
top:-150px;
right:100px;
bottom: 0;
left:0px;
content: '';
-webkit-animation: strome 5s ease-in infinite;
animation: strome 5s ease-in infinite;
z-index: 9999;
}

不可能复制:before选择器
仍然,您需要复制一些东西,因为暴光和闪光灯都使用:before
和:after
伪选择器
但是,无需重复#background
元素,因为两者都将包含背景图像,并且背景图像会重叠...因此,您将永远无法成功获得所需的渲染。
相反,尝试在后台添加2个新的div,您将在其上应用新的.storm
类,该类将使用:before
和:after
伪选择器进行风暴和闪光
有点像这样
HTML
<div id="background">
<div class="storm"></div>
<div class="storm"></div>
</div>
CSS
#background {
position: relative;
height: 100%;
width: 100%;
background: url("https://sharabindu.com/pure_css_rain_with_strom/img/storm-bg.jpg") center center;
background-size: cover;
background-repeat: no-repeat;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-webkit-user-select: none;
}
.storm{position: absolute; height: 100%; width: 50%;}
.storm:nth-of-type(1){left: 0;}
.storm:nth-of-type(2){right: 0;}
.storm:after {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
content: '';
-webkit-animation: flash 5s ease-in infinite;
animation: flash 5s ease-in infinite;
z-index: 50;
}
.storm:before {
position: absolute;
top: -150px;
right: 100px;
bottom: 0;
left: 0px;
content: '';
-webkit-animation: strome 5s ease-in infinite;
animation: strome 5s ease-in infinite;
z-index: 9999;
}
现在...左右风暴都将同步,这不会提供最佳效果...现在由您决定向前移动
