我想更改引导程序崩溃的断点。我在堆栈上找到了一些很棒的答案,但它们似乎在我的导航栏上无法正常工作
现在,当屏幕宽度达到991px时,我的导航栏会有额外的CSS来缩小
@media (max-width: 991px) {
.navbar-header {
float: none;
}
.navbar-toggle {
display: block;
}
.navbar-collapse {
border-top: 1px solid transparent;
box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
}
.navbar-collapse.collapse {
display: none!important;
}
.navbar-nav {
float: none!important;
margin: 7.5px -15px;
}
.navbar-nav>li {
float: none;
}
.navbar-nav>li>a {
padding-top: 10px;
padding-bottom: 10px;
}
.navbar-text {
float: none;
margin: 15px 0;
}
/* since 3.1.0 */
.navbar-collapse.collapse.in {
display: block!important;
}
.collapsing {
overflow: hidden!important;
}
}
当我调整浏览器大小时,我会发生什么:(请参阅我的问题的红色箭头)。
某些链接不在导航栏中。我希望它的工作原理完全相同,当我将屏幕缩小并且原始的Bootstrap代码开始用于移动设备时(它只是在导航栏中添加一个滚动条,所有菜单元素都在导航栏内。
以下是导航栏的html代码:
<nav class="navbar navbar-inverse navbar-fixed-top yellow_border_navigation">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<li>
<a href="index.php"><img src="images/SingleLogo.png" height="64"></a>
</li>
<li class="dropdown navigation_link_margin">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">Home
<span class="caret"></span></a>
<ul class="dropdown-menu">
<li><a href="index.php">Home</a></li>
<li><a href="index.php#IndexAbout">About</a></li>
<li><a href="index.php#IndexContact">Contact</a></li>
</ul>
</li>
<?php if(isset($_SESSION['id'])){?>
<li class="navigation_link_margin"><a href="profile.php">Profile</a></li>
<?php } ?>
<li class="navigation_link_margin"><a href="clubs.php">Clubs</a></li>
<li class="navigation_link_margin"><a href="tournaments.php">Tournaments</a></li>
<li class="navigation_link_margin"><a href="leaderboard.php">Leaderboard</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<?php if(!isset($_SESSION['id'])){?>
<li><a href="#registerModal" data-toggle="modal"><span class="glyphicon glyphicon-user"></span> Register</a></li>
<li><a href="#LoginModal" data-toggle="modal"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
<?php } else { ?>
<li><a href="message.php"><?php navigation_display_new_messages(); ?></a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#"><?php echo navigation_get_first_name(); ?>
<span class="caret"></span></a>
<ul class="dropdown-menu">
<?php side_menu_display(); ?>
<li><a href="account.php"><span class="glyphicon glyphicon-user"></span> Account</a></li>
<li><a href="credits.php"><span class="glyphicon glyphicon-asterisk"></span> Credits</a></li>
<li><a href="index.php?logout"><span class="glyphicon glyphicon-record"></span> Log Out</a></li>
</ul>
</li>
<?php } ?>
</ul>
</div>
</div>
</nav>

Bootstrap设置的最大高度是剪切移动导航栏。你可以像这样覆盖...
.collapse.in{
display:block !important;
max-height: initial;
}

默认情况下,小型设备的Bootstrap断点为768px。 假设您有bootstrap.css文件(不是缩小版本),您可以通过将相应的768px值更改为991px来直接更改该文件中的断点。
然而,更简单的解决方案是通过以下通用代码覆盖它,但它不是最干净,也不是最有效的方法:
@media (max-width: 991px) {
.navbar-header {
float: none;
}
.navbar-left,.navbar-right {
float: none !important;
}
.navbar-toggle {
display: block;
}
.navbar-collapse {
border-top: 1px solid transparent;
box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
}
.navbar-fixed-top {
top: 0;
border-width: 0 0 1px;
}
.navbar-collapse.collapse {
display: none!important;
}
.navbar-nav {
float: none!important;
margin-top: 7.5px;
}
.navbar-nav>li {
float: none;
}
.navbar-nav>li>a {
padding-top: 10px;
padding-bottom: 10px;
}
.collapse.in{
display:block !important;
}
}
另外你应该使用&#34; navbar-brand&#34;您的徽标的类,并将其放在汉堡菜单按钮后面:
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="index.php">
<img src="iimages/SingleLogo.png" alt="">
</a>
