我已經在我的rails應用中實現了這個:animated header。一切工作正常,但我想改變標題圖像,並由於某種原因,它不會加載......我已經嘗試了不同的頁面加載圖像相同的語法,它在軌道中工作正常。背景圖像不會加載圖像Ruby on Rails
我該如何做這項工作,我錯過了什麼?
我改變CSS代碼
.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;
}
