我希望在较小的屏幕(如手机和平板电脑)上查看时,我将导航栏转换为下拉菜单。问题是,我没有使用传统的bootstrap导航栏系统,只是自己做了。我知道通常的bootstrap解决方案涉及使用nav类,但我不确定如何将它们集成到我自己的代码中,因为我没有使用它们开始。对于平板电脑,我希望主菜单按钮隐藏在带有切换按钮的下拉菜单中,同时保留徽标。这是我的代码:
<header class="main-header" id="Navigation">
<div class="container-fluid">
<div class="row">
<div class="col-md-3">
<img class="HeaderLogo img-responsive" src="http://res.cloudinary.com/duocsoiqy/image/upload/v1499450095/Enpowered_Logo_k69cqw.png">
</div>
<div class="col-md-6 text-center">
<div class="row text-center">
<div class="col-md-2 offset-md-1">
<p class="NavBarButtons"> WHY US </p>
</div>
<div class="col-md-2">
<p class="NavBarButtons"> FIX YOUR BILL </p>
</div>
<div class="col-md-2">
<p class="NavBarButtons"> HOW IT WORKS </p>
</div>
<div class="col-md-2">
<p class="NavBarButtons"> LEARN WITH US </p>
</div>
<div class="col-md-2">
<p class="NavBarButtons"> COMMERCIAL </p>
</div>
</div>
</div>
<div class="col-md-3">
<div class="row">
<div class="col-md-3 offset-md-4">
<p class="NavBarButtons"> LOG IN </p>
</div>
<div class="col-md-4 md-offset-3">
<button class="SignUp"><b> UNLOCK YOUR POWER </b></button>
</div>
</div>
</div>
</div>
</div>
</header>
由于我使用了网格系统,所有内容都崩溃到一定程度,然后整个标题完全混乱并堆叠,这就是为什么我想尝试让菜单按钮在达到该断点时进入下拉菜单。任何帮助都非常感谢。谢谢!

当您尝试在.navbar
之外执行此操作时,您会丢失许多内置功能,但它是可管理的。 .navbar-collapse
组件本身并不直接与较大组件的使用相关联;你只需要包含崩溃的<button>
和包装元素:
<header class="main-header" id="Navigation">
<div class="container-fluid">
<div class="row">
<div class="col-xs-3">
<img class="HeaderLogo img-responsive" src="http://res.cloudinary.com/duocsoiqy/image/upload/v1499450095/Enpowered_Logo_k69cqw.png">
</div>
<div class="col-xs-9 text-right">
<div class="row">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#menu-collapse" 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>
<div class="collapse navbar-collapse text-center" id="menu-collapse">
<div class="col-md-2"><p class="NavBarButtons">WHY US</p></div>
<div class="col-md-2"><p class="NavBarButtons">FIX YOUR BILL</p></div>
<div class="col-md-2"><p class="NavBarButtons">HOW IT WORKS</p></div>
<div class="col-md-2"><p class="NavBarButtons">LEARN WITH US</p></div>
<div class="col-md-2"><p class="NavBarButtons">COMMERCIAL</p></div>
<div class="col-md-1"><p class="NavBarButtons">LOG IN</p></div>
<div class="col-md-1"><button class="SignUp"><b>UNLOCK YOUR POWER</b></button></div>
</div>
</div>
</div>
</div>
</div>
</header>
...
如果您遇到问题(以及为什么我建议使用整个.navbar
结构,您需要设置上述按钮及其各种状态的样式。您还需要解决间距问题(下拉列表以这种方式向下推动元素。)

它非常讨厌,但是......您可以通过对代码进行一些调整来实现,以便您最终得到这个:
<nav class="main-header navbar navbar-default" id="Navigation">
<div class="container-fluid">
<div class="col-md-3 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 class="HeaderLogo img-responsive" src="http://res.cloudinary.com/duocsoiqy/image/upload/v1499450095/Enpowered_Logo_k69cqw.png" style="width: auto;">
</a>
</div>
<div class="col-md-6 text-center collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="text-center nav navbar-nav">
<li class="col-md-2 offset-md-1">
<p class="NavBarButtons"> WHY US </p>
</li>
<li class="col-md-2">
<p class="NavBarButtons"> FIX YOUR BILL </p>
</li>
<li class="col-md-2">
<p class="NavBarButtons"> HOW IT WORKS </p>
</li>
<li class="col-md-2">
<p class="NavBarButtons"> LEARN WITH US </p>
</li>
<li class="col-md-2">
<p class="NavBarButtons"> COMMERCIAL </p>
</li>
</ul>
</div>
<div class="col-md-3">
<div class="row">
<div class="col-md-3 offset-md-4">
<p class="NavBarButtons"> LOG IN </p>
</div>
<div class="col-md-4 md-offset-3">
<button class="SignUp"><b> UNLOCK YOUR POWER </b></button>
</div>
</div>
</div>
</div>
</nav>
这就是我的所作所为:
col-md-3
课程navbar-header
在那里添加
<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>
在<a class="navbar-brand" href="#">
img
col-md-6
列,添加类collapse navbar-collapse
和
id="bs-example-navbar-collapse-1"
该中的div添加了类nav navbar-nav
制作header
一个nav
元素
提供nav
课程navbar navbar-default
删除行
col-md-6
列中的div,删除该行并将其设为ul
将div
中的li
转换为toggle
s
基本上你现在所做的就是采取必要的步骤来编写一个bootstrap导航。仔细看看http://getbootstrap.com/components/#navbar处的示例 您会发现它实际上并没有使用网格系统。
请注意,您需要包含引导程序javascript才能使用<script src="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
功能。
p
另外,请勿在导航中添加include 'database.php';
$user = $_POST['user'];
$gender = $_POST['gender'];
$description = $_POST['description'];
if (isset($user) && isset($gender) && isset($description) && $user != '' && $gender != '' && $description != '') {
$insert_query = "INSERT INTO my_table user, gender, description VALUES '$user','$gender', '$description'";
$rks = mysqli_query($con, "SELECT up_votes, down_votes FROM my_table ORDER BY id DESC LIMIT 1");
$row = mysqli_fetch_row($rks);
if (mysqli_query($con, $insert_query)) {
$insert = array($user, $gender, $description, $row[0], $row[1]);
echo json_encode($insert);
} else {
echo mysqli_error($con);
}
} else {
echo 'Failed: ' . mysqli_error($con);
}
个元素。段落在那里没有任何意义。
