我在我的应用程序中使用 Bootstrap 模式，它可能有很长的内容。我在不同的页面中有 2 个模式。当我在移动设备中查看我的模态时，我可以滚动其中一个模态，但不能滚动我的第二个模态。当我尝试滚动它时，背景会滚动。即使当我在模态内部单击时，模态似乎也没有聚焦。我以为我必须在我的每个模态中添加不同的模态属性，但模态代码对于两者都是相同的，例如:
<div class="modal fade" id="modalFeedback" data-keyboard="false" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-lg modal-dialog-centered" role="document">
我不知道为什么会这样
最佳答案
请试试这段代码是否正常工作:
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
