html - 在 bootstrap5 中居中图像

问题描述

我是 Bootstrap 的新手，我有一个非常简单的网络，只有一个导航。我希望页面使用导航按钮进行响应。但是当我部署菜单时，facebook 徽标没有居中，我猜这是因为 a 标签更大。

.imagen-logo{
  width: 4rem;
  transition: all 0.25s;
}
.facelogo{
  width: 3rem;
  height: 3rem;
  transition: all 0.25s;
}
.facelogo:hover{
  width: 3.5rem;
  height: 3.5rem;
}
