Question

当我点击button然后button模型显示时，我创建了一个popup但它会隐藏在页面正文旁边，当我滚动时按钮也会隐藏。我希望弹出窗口时出现然后我无法滚动我的页面正文。我使用bootstrap创建了模型弹出窗口。这是截图LINK

如果我理解正确你想要模态在所有其他元素之上。你需要找出那个体的最高z指数，然后把一个比你的模态更大的z指数。假设您的导航菜单或右下角弹出窗口的z-index值为50，则需要至少将模态设置为51。像这样的东西 -

.modal {
    /* ... rest of your css ... */
    z-index: 51;
    /* ... rest of your css ... */
}

滚动时弹出模型隐藏在身体旁边？
