Question

我在尝试增加主导航内部导航栏品牌形象的大小时遇到了一些问题。看起来它不会更大50px。我希望它大约100px高，但似乎无法解决如何做到这一点。我目前将它放在导航中心，旁边有汉堡菜单。

有人知道如何实现我想做的事吗？

HTML：

 .navbar-brand {
    background: url(../img/logo.png);
    background-position: center;
    background-repeat: no-repeat;
    background-size: contain;
    width: 300px;
    transform: translateX(-50%);
    left: 50%;
    position: absolute;
    padding: 0;
  }

.navbar-default .navbar-toggle .icon-bar {
  background-color: #fff;
}

.navbar .navbar-nav {
  display: inline-block;
  float: none;
  vertical-align: top;
}

.navbar .navbar-collapse {
  text-align: center;
}

.custom-nav {
  color: #fff;
  background: #718373;
  border-radius: 0;
  margin-bottom: 0;
  border: 0;
}

.custom-nav .navbar-nav>li>a {
  color: #fff;
  margin: 0 auto;
}

.custom-nav .navbar-nav>li>a:hover,
.custom-nav .navbar-nav>li>a:focus {
  color: #fff;
}

.navbar-default .navbar-toggle:focus,
.navbar-default .navbar-toggle:hover {
  background: none;
}

.custom-nav .navbar-nav>.open>a,
.custom-nav .navbar-nav>.open>a:focus,
.custom-nav .navbar-nav>.open>a:hover {
  color: #fff;
  background: none;
}

.custom-nav .navbar-nav li {
  margin: 0 auto;
  text-align: center;
  width: 150px;
}

.dropdown-menu {
  padding: 0;
  margin: 0;
  background: #718373;
  border: none;
  box-shadow: none;
  min-width: 90px;
}

.dropdown-menu li:last-child a {
  margin-bottom: 10px;
}

.dropdown-menu>li>a {
  display: block;
  clear: both;
  font-weight: normal;
  color: #fff;
  width: 95%;
  margin: 0 auto;
  text-align: center;
  padding: 20px 0;
}

.dropdown-menu>li>a:focus,
.dropdown-menu>li>a:hover {
  color: #fff;
  text-decoration: none;
  background: none;
  outline: 2px solid white;
  outline-offset: -2px;
}

CSS：

.navbar-header .navbar-brand {
  height: 100px;
}

这就是目前的看法

Bootstraps导航栏样式会覆盖您的样式。使用higher specificity将您的样式应用于导航栏品牌，例如与

.navbar-header .navbar-brand {
  height: 100px;
}

这样你可以覆盖身高。

.navbar-header .navbar-brand {
  background: url(../img/logo.png);
  background: url(//placehold.it/300x100);
  background-position: center;
  background-repeat: no-repeat;
  background-size: contain;
  height: 100px;
  width: 300px;
  transform: translateX(-50%);
  left: 50%;
  position: absolute;
  padding: 0;
  : #fff;
}
.navbar .navbar-nav {
  display: inline-block;
  float: none;
  vertical-align: top;
}
.navbar .navbar-collapse {
  text-align: center;
}
.custom-nav {
  color: #fff;
  background: #718373;
  border-radius: 0;
  margin-bottom: 0;
  border: 0;
}
.custom-nav .navbar-nav>li>a {
  color: #fff;
  margin: 0 auto;
}
.custom-nav .navbar-nav>li>a:hover,
.custom-nav .navbar-nav>li>a:focus {
  color: #fff;
}
.navbar-default .navbar-toggle:focus,
.navbar-default .navbar-toggle:hover {
  background: none;
}
.custom-nav .navbar-nav>.open>a,
.custom-nav .navbar-nav>.open>a:focus,
.custom-nav .navbar-nav>.open>a:hover {
  color: #fff;
  background: none;
}
.custom-nav .navbar-nav li {
  margin: 0 auto;
  text-align: center;
  width: 150px;
}
.dropdown-menu {
  padding: 0;
  margin: 0;
  background: #718373;
  border: none;
  box-shadow: none;
  min-width: 90px;
}
.dropdown-menu li:last-child a {
  margin-bottom: 10px;
}
.dropdown-menu>li>a {
  display: block;
  clear: both;
  font-weight: normal;
  color: #fff;
  width: 95%;
  margin: 0 auto;
  text-align: center;
  padding: 20px 0;
}
.dropdown-menu>li>a:focus,
.dropdown-menu>li>a:hover {
  color: #fff;
  text-decoration: none;
  background: none;
  outline: 2px solid white;
