Navbar页面高度的百分比

我想要的是我的导航栏是页面高度的5％，最小值为128px，这样我的标志总是至少为128px或更大。Navbar页面高度的百分比

问题是，这只是填充页面，似乎是使用标志大小的某些原因。

代码：

.navbar { 
 
    background-color: #1b1b1b; 
 
} 
 

 
.navbar>.container-fluid 
 
.navbar>.container-fluid>.navbar-header, 
 
.navbar>.container-fluid>.navbar-header>.navbar-brand{ 
 
    height: inherit; 
 
} 
 

 
.navbar>.container-fluid { 
 
    margin-left: 18%; 
 
    margin-right: 18%; 
 
    padding-left: 0; 
 
    padding-right: 0; 
 
} 
 

 
.navbar-brand>img { 
 
    height: 100%; 
 
    width: auto; 
 
} 
 

 
.navbar-default .navbar-nav>li>a{ 
 
    color: white; 
 
}

我已经看到了这个工作后，设置html，body {height：100％;}但是你确定这是你想要的吗？景观桌面上的5％高度在纵向平板电脑或手机中的视觉上不同。 – Juan

给height: 5vh; min-height: 128px;到navbar-header，height: 100%到container-fluid和height: inherit到navbar-header和navbar-brand

.navbar { 
 
    background-color: #1b1b1b; 
 
} 
 

 
.navbar>.container-fluid>.navbar-header, .navbar>.container-fluid>.navbar-header>.navbar-brand{ 
 
    height: inherit; 
 
} 
 

 
.navbar>.container-fluid { 
 
    margin-left: 18%; 
 
    margin-right: 18%; 
 
    padding-left: 0; 
 
    padding-right: 0; 
 
    height: 100%; 
 
} 
 

 
.navbar-brand>img { 
 
    height: 100%; 
 
    width: auto; 
 
} 
 

 
.navbar.navbar-default { 
 
    height: 5vh; 
 
    min-height: 128px; 
 
} 
 

 
.navbar-default .navbar-nav>li>a{ 
 
    color: white; 
 
}

如果检查元素（分别div.navbar-brand和img），你会看到，第一：.navbar品牌有height: inherit;这意味着它将继承。所以很多方法可以解决这个问题一个是给.navbar-brand一个height: 128px;

尝试使用'height：5vh;最小高度：128px' – dave
