如何将导航栏菜单放在徽标下方？

Question

我使用自定义CSS和引导程序类名构建了此标头。我已经尝试过z-index，float: initial属性。提前致谢

.branding-preview {
    height: 75px;
    margin-left: 15px;
    margin-right: 15px;
    background-color: #0071bb;
}

.branding-logo {
    float: left;
    height: 50px;
    font-size: 18px;
    padding: 15px 15px;
}

.branding-logo img {
    width: 300px;
    height: 50px;
}

.branding-powered-by-logo {
    float: right;
    height: 50px;
    color: white;
    font-size: 15px;
    padding: 2px 10px;
}

.preview-menu {
    margin: 30px 0 0 0;
}

.preview-menu > li > a {
    margin: 0 3px;
    color: white;
    text-transform: uppercase;
    border-bottom: solid 1px transparent;
    background-color: transparent !important;
}

<div class="branding-preview">
	<div class="branding-logo">
		<img id="branding-logo" src="/path/to/logo">
	</div>
	<div class="branding-powered-by-logo">
		<span>Powered By</span>
		<img id="branding-powered-by-logo" src="/path/to/logo" height="30">
	</div>
	<ul class="navbar-nav navbar-right nav preview-menu">
		<li><a>Start</a></li>
		<li><a>Plan</a></li>
		<li><a>Manage</a></li>
		<li><a>Learn</a></li>
		<li><a>Admin</a></li>
	</ul>
</div>

Answer 1

我想你只需要在你的.preview-menu类中添加position:absolute; right:0px;。

Answer 2

没有所有的CSS规则并不简单，但概念是：创建一个浮动到右边和内部的包装器创建2行，一个用于branding-powered-by-logo和display:block，第二行依赖于实际的CSS但可能无需修改任何东西。

如果您可以发布真实页面，我们可以更精确地帮助您。希望这对你有所帮助。

.branding-preview {
    display:block;
    height: 75px;
    margin-left: 15px;
    margin-right: 15px;
    background-color: #0071bb;
}

.branding-logo {
    float: left;
    height: 50px;
    font-size: 18px;
    padding: 15px 15px;
}

.branding-logo img {
    width: 300px;
    height: 50px;
}

.branding-powered-by-logo {
    /* ADDED */
      display:block;
      text-align:right;
    
    height: 50px;
    color: white;
    font-size: 15px;
    padding: 2px 10px;
}

.preview-menu {
    margin: 0px 0 0 0;
}

.preview-menu > li > a {
    margin: 0 3px;
    color: white;
    text-transform: uppercase;
    border-bottom: solid 1px transparent;
    background-color: transparent !important;

.wrapper-logo-navbar {
