Fixed navigation bar

The top and bottom of the main content of the page are covered by the fixed navigation bar. In order to prevent the fixed navigation bar from covering the content, we need to do some processing on the body:

body {
padding-top: 70px;/*有顶部固定导航条时设置*/
padding-bottom: 70px;/*有底部固定导航条时设置*/
}
<div class="navbar navbar-default navbar-fixed-top" role="navigation">
 …
</div>
Copy after login

In fact, in addition to this solution, we have other solutions, placing the fixed navigation bar on the page content Front:

<div class="navbar navbar-default navbar-fixed-bottom" role="navigation">
 …
</div>
<div class="content">我是内容</div>
Copy after login

Add the following style code in the file:

.navbar-fixed-top ~ .content {
padding-top: 70px;
}
.navbar-fixed-bottom ~ .content {
padding-bottom: 70px;
}
Copy after login
