css - 每当我滚动我的页面时，我的背景也会滚动如何解决这个问题？

Question

这是我的CSS代码

.bg-main {
    background: linear-gradient(0deg,rgba(0,0,0,0.5),rgba(0,0,0,0.5)), url(../img/mother.png) no-repeat center center fixed !important; 
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover !important;
}

Answer 1

从它的样式中移除fixed。

background: linear-gradient(0deg,rgba(0,0,0,0.5),rgba(0,0,0,0.5)), url(../img/mother.png) no-repeat center center !important; 
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover !important;
