设置背景及背景是否可滚动
我们可以在弹出侧边栏的时候设置 <body> 元素是否可以滚动，也可以设置是否显示一个背景画布。 使用 data-bs-scroll 属性来设置 <body> 元素是否可滚动，data-bs-backdrop 来切换是否显示背景画布。
实例
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasScrolling" aria-controls="offcanvasScrolling">body 元素可以滚动</button>
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasWithBackdrop" aria-controls="offcanvasWithBackdrop">显示画布(默认)</button>
<button class="btn btn-primary" type="button" data-bs-toggle="offcanvas" data-bs-target="#offcanvasWithBothOptions" aria-controls="offcanvasWithBothOptions">允许滚动及显示画布</button>
<div class="offcanvas offcanvas-start" data-bs-scroll="true" data-bs-backdrop="false" tabindex="-1" id="offcanvasScrolling" aria-labelledby="offcanvasScrollingLabel">
<div class="offcanvas-header">
<h5 class="offcanvas-title" id="offcanvasScrollingLabel">正文内容可以滚动</h5>
<button type="button" class="btn-close text-reset" data-bs-dismiss="offcanvas" aria-label="Close"></button>
</div>
<div class="offcanvas-body">
