导航栏中的徽标垂直对齐不起作用
我正在尝试将“徽标”与导航栏垂直对齐。我希望它在正常状态和折叠状态下居中。
我尝试了一些可能的解决方案，但到目前为止似乎没有任何效果。我尝试添加不同的头寸类型，例如，我尝试使用保证金顶部和底部 50%。可能有一个非常简单的方法来实现这一切。

我调整了您的 JSFiddle 以display: flex使用align-items: center https://jsfiddle.net/xv29r1sm/ -

也许这就是你想要的在 css 部分中，搜索#navbar.shrink img。从那里删除这一行： margin-top: -30px;或者像这样评论它： /* margin-top: -30px; */现在它应该垂直居中。那是因为 margin-top 属性会将图像进一步拖动到顶部，这在您的情况下是不需要的。 //header Effekt beim scrollen$(function() { var shrinkHeader = 100;

margin: auto是你的朋友吗？将其应用于子 div。另请检查弹性盒的用法
