css - IMG 和文本未在我的导航栏中的 Bootstrap 按钮中对齐

Question

所以我环顾了 Stackoverflow，找不到解决我问题的方法

奇怪的是

我在这里试试，codepen

<nav>
  <button class="btn btn-primary"> signed in as fermi 
    <img src="https://ui-avatars.com/api/?
     name=Fermi+Fang&background=0D8ABC&color=fff&rounded=true">
  </button>
</nav>

文本完美居中，

但在我的实时代码中，它没有

img of my live code

好的，这是我的 live code

   nav(class="navbar navbar-expand-md fixed-top navbar-light bg-none 
px-sm-4 px-0 pr-2")
  button(id="container" class="navbar-toggler pr-0 ml-0 pl-3"

          a(role="button" class="btn m-1 btn-mob d-md-none" 
href="/logout") Log Out

    //hidden in mobile view
    ul(class="navbar-nav mr-2")
      if isLoggedIn

      else
        li(class="nav-item")
          button(type="button" class="btn btn-primary m-1 d-none d-md-
block" data-toggle="modal" data-target="#signUpModal") Sign Up
        li(class="nav-item")
          button(type="button" class="btn btn-outline-primary m-1 d-
none d-md-block" data-toggle="modal" data-target="#logInModal") Log In

有什么线索可能导致我的按钮中的文本和 img 未正确对齐吗？

谢谢，

尝试将 line-height 更新为与 font-size 相同的大小。也许它适合你。
