标签: html css jsp twitter-bootstrap-3 navbar

我正在尝试将我的徽标对齐到左侧,并将其置于该位置的导航栏中心。我尝试了一些不同的东西但没有成功,由于某种原因,我无法用底部填充来移动它。如果有人能提供一些帮助,那就太好了。我的徽标是800x800,这就是为什么我将它的大小调整为45px

这是我的代码:

<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">
            <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 pull-left" href="#"><img id="logo" src="${pageContext.servletContext.contextPath}/static/images/nfl.gif"></a>
    </div>

    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <ul class="nav navbar-nav">
            <li class="active"><a href="#">Conferences <span class="sr-only">(current)</span></a></li>
            <li><a href="#">Divisions</a></li>
            <li class="dropdown">
                <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
                <ul class="dropdown-menu" role="menu">
                    <li><a href="#">Action</a></li>
                    <li><a href="#">Another action</a></li>
                    <li><a href="#">Something else here</a></li>
                    <li class="divider"></li>
                    <li><a href="#">Separated link</a></li>
                    <li class="divider"></li>
                    <li><a href="#">One more separated link</a></li>
                </ul>
            </li>
        </ul>
        <form class="navbar-form navbar-left" role="search">
            <div class="form-group">
                <input class="form-control" placeholder="Search" type="text">
            </div>
            <button type="submit" class="btn btn-default">Submit</button>
        </form>
        <ul class="nav navbar-nav navbar-right">
            <li><a href="#">Link</a></li>
        </ul>
    </div>
</div>

#logo
{
float: left;
width:45px;
padding-bottom: 50px;
}

.nav {
float:left;
}

您可以使用text-align将其居中:

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

添加height:100%以获得父亲的身高:

#logo {
 float: left;
 width:45px;
 height:100%;
}

并且您想要适合您的徽标,然后删除包装器的填充:

.navbar-brand {
   text-align:center;
   padding:0 !important;
   margin:0;
}

&#13;
.navbar-brand {
  text-align:center;
  margin:0 !important;
  /*padding:0 !important;*/ /*uncomment to fit*/  
}
#logo
{
float: left;
width:45px;
height:100%;
}

.nav {
float:left;
}
