z-index不使用模态弹出扩展器

问题描述 投票：0回答：1

有一个背景图像，上面放置一个div。现在有一个登录模式，它应该出现在点击顶部的div上。但它在某种程度上出现在div下面。预期结果从底部到顶部背景图像然后div然后弹出。以下是我提供的图像：https://i.stack.imgur.com/eCD9z.png预期的结果是popup应该在顶部

将div的z-index设置为0和1.默认情况下，弹出窗口z-index为10001但仍然div位于其顶部。

<style>
       body, html
       {
           height: 100%;
           margin: 0;

    </div>

答案是第一个最顶级的div标签应该在modalpopupextender上面完成。早些时候，它在代码结束时完成。感谢你的帮助。
