我已经在我的rails应用中实现了这个:animated header。一切工作正常,但我想改变标题图像,并由于某种原因,它不会加载......我已经尝试了不同的页面加载图像相同的语法,它在轨道中工作正常。背景图像不会加载图像Ruby on Rails
我该如何做这项工作,我错过了什么?
我改变CSS代码
.header:before {
content: "";
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
-webkit-backface-visibility: hidden;
-webkit-transform: translateZ(0) scale(1.0, 1.0);
transform: translateZ(0);
background-image: asset-data-url("header_background.jpg");
background-repeat: no-repeat;
background-attachment: fixed;
background-position: top center;
background-color: #1B2030;
background-size: cover;
-o-background-size: cover;
-webkit-background-size: cover;
-moz-background-size: cover;
animation: grow 60s linear 10ms infinite;
transition: all 0.2s ease-in-out;
z-index: -2;
}
从codepen
.header:before{
content:"";
width:100%;
height:100%;
position:absolute;
top:0;
left:0;
-webkit-backface-visibility: hidden;
-webkit-transform: translateZ(0) scale(1.0, 1.0);
transform: translateZ(0);
background:#1B2030 url(https://unsplash.it/1999/999?image=1063) top center no-repeat;
background-size:cover;
background-attachment:fixed;
animation: grow 60s linear 10ms infinite;
