移动safari忽略z索引
Mobile safari ignoring z-index
尝试单击此处的缩略图之一:http://henrybuilt.com/questions/
在计算机上,它可以根据需要工作(文本覆盖显示在幻灯片集中的第一个图像的顶部,然后在单击下一个或上一个时消失)。在safari和chrome版本的iPad或iPhone上,文本覆盖会出现一秒钟,一旦加载,就会被我的背景图像幻灯片div覆盖,我无法将我的覆盖(.slide_view.title)显示在背景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;
}
