【问题描述】：
我正在使用 bootstrap 5 off-canvas 进行折叠，同时我有一个公告栏，它只是我导航栏顶部的一个可关闭警报。 p>
问题是当我点击时，我的画布外上衣尺寸效果不佳 关闭可关闭警报的按钮。
我该如何解决这个问题？我在codepen.Io做了一个活生生的例子
注意：尝试调整窗口大小并关闭警报以查看问题 我在画布上的。
HTML/CSS/JS：
(function () {
'use strict'
// for Off-Canvas Menu
document.querySelector('[data-bs-toggle="offcanvas"]').addEventListener('click', function () {
document.querySelector('.offcanvas-collapse').classList.toggle('open')
})
})() @media (max-width: 991.98px) {
.offcanvas-collapse {
position: fixed;
top: 56px; /* Height of navbar */
bottom: 0;
left: 100%;
width: 100%;
padding-right: 1rem;
padding-left: 1rem;
overflow-y: auto;
visibility: hidden;
background-color: #343a40;
transition: transform .3s ease-in-out, visibility .3s ease-in-out;
}
.offcanvas-collapse.open {
visibility: visible;
transform: translateX(-100%);

<h1>What is Lorem Ipsum?</h1>
<p class="lead">
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
