修复了iFrame内部的NavBar

Question

I am trying to create a fixed navbar using bootstrap, the page works fine when on its own, however when I put this page inside of an iframe, the navbar scrolls down with the page. The code below has been taken from the bootstrap documentation. Note that this works fine on Desktops, however when using an iPad or iPhone to try it, this is where the problem occurs.

NavBar.html

<!-- Fixed navbar -->
<nav class="navbar navbar-default navbar-fixed-top">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
        <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="#">Project name</a>
    </div>
    <div id="navbar" class="navbar-collapse collapse">
      <ul class="nav navbar-nav">
        <li class="active"><a href="#">Home</a></li>
        <li><a href="#about">About</a></li>
        <li><a href="#contact">Contact</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 class="divider"></li>
            <li class="dropdown-header">Nav header</li>
            <li><a href="#">Separated link</a></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">

Answer 1

Its worked well for me, Try this out, hope it will resolve your issue.

Add a class to your iframe and add these properties in css

.classname{
    height: 99%;
    overflow: hidden;
    width: 100%;
}
