我是 Bootstrap 新手，并尝试自定义 Bootstrap 的现有示例。我的目标是将 div 标签（id 为“inner”）扩展到屏幕的全宽。
我尝试了很多不同的方法，但似乎不起作用，包括重置水平方向的边距和填充。我还尝试在 id 为“outer”的 div 标签上使用 flex-box，但它不起作用。对于之前的所有方法，由于某种原因，“内部”div 标签不再位于中心。
我使用的最后一种方法是创建一个新的 div.container-fluid 标签，该标签位于“外部”标签内并覆盖整个“内部”div 标签。然而，效果并不好。

您需要添加一个 ccss 文件，其中包含以下行“min-width: 100%！重要！”以“覆盖”#outer 和 #inner div 的 bootstrap css
#outer{
min-width: 100% !important;
/* padding: 0 !important;
margin: 0 !important; */
}
#inner{
min-width: 100% !important;
padding: 0 !important;
margin: 0 !important;
}<body>
<div class="container my-5" id = "outer">
<div class="p-5 text-center bg-body-tertiary rounded-3" id = "inner">
<svg class="bi mt-4 mb-3" style="color: var(--bs-indigo);" width="100" height="100"><use xlink:href="#bootstrap"></use></svg>
