Question

我试图让这个页面反应灵敏，但在很多次失败之后我就陷入了困境。任何人都可以告诉我为什么顶部有一个白色边框，图像也不适合页面？

CSS：

.cb-slideshow,
.cb-slideshow:after { 
    position: fixed;
    width: 100%;
    height: 100%;
    top: 0px;
    left: 0px;
    z-index: 0; 
}
ul {
    list-style-type: none;  
}
.cb-slideshow:after { 
    content: '';
    margin-top:0px
}
.cb-slideshow li span { 
    width: 100%;
    height: 100%;

Answer 1

给.cb-slideshow{margin-top:0px}。根据需要使用.cb-slideshow li span{background-position: 50% 50%;}播放背景图片。

CSS响应能力不起作用
