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忽略的警报。

问题是当我在可关闭警报上单击关闭按钮时，我的画布外上衣尺寸效果不佳。

我该如何解决这个问题？我在codepen.Io上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我在画布外遇到的问题。

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%);
      }
    }

     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.

确保您正确使用Offcanvas 组件...

标记：

<div class="offcanvas offcanvas-start" tabindex="-1" id="offcanvas" aria-labelledby="offcanvasLabel">
  <div class="offcanvas-header">
    <h5 class="offcanvas-title" id="offcanvasLabel">Offcanvas</h5>
    <button type="button" class="btn-close text-reset" data-bs-dismiss="offcanvas" aria-label="Close"></button>
  </div>
  <div class="offcanvas-body">
    Content for the offcanvas goes here. You can place just about any Bootstrap component or custom elements here.
  </div>
</div>

JS：

var offcanvasElementList = [].slice.call(document.querySelectorAll('.offcanvas'))
var offcanvasList = offcanvasElementList.map(function (offcanvasEl) {
  return new bootstrap.Offcanvas(offcanvasEl)
})
