Question

我已经使用bootstrap对导航条进行了编码，并且它完美地工作但是当我在iPad上尝试它时，无论是纵向还是横向，它都不会崩溃。我尝试更改@media（我的bootstrap CSS文件的最大宽度和最小宽度部分，但仍然无法正常工作。

<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="http://www.linkhere.com/"><img src="../common/images/logo.png" width="120px" height="35px" style="vertical-align:middle"/></a>
        </div>
        <div id="navbar" class="navbar-collapse collapse">
          <ul class="nav navbar-nav">
            <li class="<?php echo c("news"); ?>"><a href="news.php">News</a></li>
