使用 W3schools 中的代码'Sidenav Overlay' 我正在尝试在 Bootstrap 中创建相同的效果。我有 .navbar-toggle 向左浮动,当叠加层向右移动时 navbar-toggle 仍然显示。不确定在出现叠加层时如何隐藏导航栏切换。第一次发帖,谢谢
CSS
.navbar {
webkit-box-shadow: 0px 2px 3px rgba(100, 100, 100, 0.49);
moz-box-shadow: 0px 2px 3px rgba(100, 100, 100, 0.49);
box-shadow: 0px 2px 3px rgba(100, 100, 100, 0.49);
background-color: white;
padding: 5px;
}
.navbar-brand {
position: absolute;
width: 100%;
left: 0;
top: 5px;
text-align: center;
margin: auto;
}
.navbar-toggle {
z-index:3;
border: none;
cursor: pointer;
float: left;
}
.navbar-toggle a:hover {
border: none;
background-color: none;
cursor: pointer;
}
/* The side navigation menu */
.sidenav {
height: 100%; /* 100% Full-height */
width: 0; /* 0 width - change this with JavaScript */
position: fixed; /* Stay in place */
z-index: 1; /* Stay on top */
top: 0;
left: 0;
background-color: #111; /* Black*/
overflow-x: hidden; /* Disable horizontal scroll */
padding-top: 60px; /* Place content 60px from the top */
transition: 0.5s; /* 0.5 second transition effect to slide in the sidenav */
}
/* The navigation menu links */
.sidenav a {
padding: 8px 8px 8px 32px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
transition: 0.3s
}
/* When you mouse over the navigation links, change their color */
.sidenav a:hover, .offcanvas a:focus{
color: #f1f1f1;
}
/* Position and style the close button (top right corner) */
.sidenav .closebtn {
position: absolute;
top: 0;
right: 25px;
font-size: 36px;
margin-left: 50px;
}
/* Style page content - use this if you want to push the page content to the right when you open the side navigation */
#main {
transition: margin-left .5s;
padding: 20px;
}
/* On smaller screens, where height is less than 450px, change the style of the sidenav (less padding and a smaller font size) */
@media screen and (max-height: 450px) {
.sidenav {padding-top: 15px;}
.sidenav a {font-size: 18px;}
}
HTML
<header>
<div class="navbar navbar-default navbar-fixed-top" role="navigation" id="slide-nav">
<div class="container">
<div class="navbar-header">
<a class="navbar-toggle" onclick="openNav()">
<span class="sr-only" >Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<a class="navbar-brand" href="#">Test Nav</a>
<div id="mySidenav" class="sidenav">
<a href="javascript:void(0)" class="closebtn" onclick="closeNav()">×</a>
<a href="#">About</a>
<a href="#">Services</a>
<a href="#">Clients</a>
<a href="#">Contact</a>
</div>
</div>
</div>
</div>
</header>
Javascript
/* Set the width of the side navigation to 250px */
function openNav() {
document.getElementById("mySidenav").style.width = "250px";
}
/* Set the width of the side navigation to 0 */
function closeNav() {
document.getElementById("mySidenav").style.width = "0";
}
最佳答案
将 z-index 添加为 99 而不是 1 到 .sidenav 类
.sidenav {
background-color: #111;
height: 100%;
left: 0;
overflow-x: hidden;
padding-top: 60px;
position: fixed;
top: 0;
transition: all 0.5s ease 0s;
width: 0;
z-index: 99;
}
