如何垂直对齐bootstrap navbar品牌？

Question

The brand is centered until i change it to an img. 该品牌一直居中，直到我将其更改为img。

I have tried many different ways of fixing it in css, but it wont work. 我尝试了多种不同的方法来修复它的CSS，但无法正常工作。

How can i vertically align this logo? 我如何垂直对齐此徽标？ and why doesnt my css work? 为什么我的CSS不起作用？ For some reason, not all of my css styles are being applied. 由于某些原因，并不是我的所有CSS样式都被应用了。

You should only need one .navbar-header div, just place the .navbar-brand into your standard .navbar-header and adjust the padding for the .navbar-brand class. 您只需要一个.navbar-header div，只需将.navbar-brand放入您的标准 .navbar-header并为.navbar-brand class.调整填充.navbar-brand class.

.navbar .navbar-brand {
  padding-top: 5px;
}

Working Example: 工作示例：

 .navbar .navbar-brand { padding-top: 5px; } .navbar .navbar-brand img { height: 40px; width: 40px; }
