如何垂直对齐自举导航栏品牌？

我已经尝试过在CSS固定的许多不同的方式，但它不会工作。

我怎么能垂直对齐这个标志？为什么我的CSS不工作？出于某种原因，并非我所有的CSS样式正在被应用。

<!DOCTYPE html> 
<html> 
<head> 

<title>Stuff</title>

<body> 

<nav class="navbar navbar-default"> 


<div class="container-fluid"> 
<div class="navbar-header"> 
<a class="navbar-brand" href="index.html"> 
<img id="logo" alt="Brand" src="images/logo.jpg" width="40px" height="40px"> 
</a> 
</div> 
<div> 


<div class="container" id="mynav"> 
    <!-- Brand and toggle get grouped for better mobile display --> 
    <div class="navbar-header"> 
     <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false"> 
     <span class="sr-only">Toggle navigation</span> 
     <span class="icon-bar"></span> 
     <span class="icon-bar"></span> 
     <span class="icon-bar"></span> 
     </button> 

    </div> 

    <!-- Collect the nav links, forms, and other content for toggling --> 
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
     <ul class="nav navbar-nav"> 
     <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li> 
     <li><a href="#">Home</a></li> 

     </ul> 

     <ul class="nav navbar-nav navbar-right"> 
     <li><a href="#">Login</a></li> 

     </ul> 
    </div><!-- /.navbar-collapse --> 
    </div><!-- /.container-fluid --> 
</nav> 

</body> 

</html>

CSS：

#mynav 
{ 
    width: 80%; 
} 

#logo 
{ 
    width:50px; 
    height: 50px; 
    vertical-align: middle; 
}

你应该只需要一个.navbar-header格，只需将.navbar-brand到您的standard.navbar-header和调整.navbar-brand class.

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

填充210

工作实施例：

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

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" /> 
 

 
<nav class="navbar navbar-default"> 
 
    <div class="container-fluid"> 
 

 
    <div class="navbar-header"> 
 

 
     <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false"> 
 
     <span class="sr-only">Toggle navigation</span> 
 
     <span class="icon-bar"></span> 
 
     <span class="icon-bar"></span> 
 
     <span class="icon-bar"></span> 
 
     </button> 
 

 
     <a class="navbar-brand" href="#"> 
 
     <img alt="Brand" src="https://unsplash.it/40/40/?random"> 
 
     </a> 
 

 
    </div> 
 

 
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
 

 
     <ul class="nav navbar-nav"> 
 
     <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a> 
 
     </li> 
 
     <li><a href="#">Home</a> 
 
     </li> 
 
     </ul> 
 

 
     <ul class="nav navbar-nav navbar-right"> 
 
     <li><a href="#">Login</a>
