尝试单击此处的其中一个缩略图:http://henrybuilt.com/questions/

在计算机上它可以按预期工作(文本覆盖显示在幻灯片集中第一张图像的顶部,然后在单击下一张或上一张时消失)。在 iPad 或 iPhone 上的 safari 和 chrome 中,文本覆盖会出现一秒钟,然后在加载后被我的背景图像幻灯片 div 覆盖,我无法使我的覆盖 (.slide_view .title) 出现在背景 div 的顶部。

具体的css:

        .slide_view .title{
display: none;
position: absolute;
top:0;
left:0;
background-color: white;
width: 100%;
height: 100%;
z-index: -3
}
#backstretch{
z-index: -3;
}

最佳答案

请更新以下 CSS 代码:

.prev, .next{z-index:999999}
.slide_view .title{z-index:999}
.slide_view .text{z-index:9999}
