<nav id="nav" class="navbar clearfix" role="navigation"> <a href="#nav" title="Show navigation">Show navigation</a>
               <div class="container-fluid clearfix">
                  <div class="navbar-header clearfix">
                     <!-- Logo -->

                     <div class="burger-menu">

                        echo do_shortcode('[menu name="main-menu"]');

                     ?>

                        <div class=" search-form clearfix">
                           <form class="search" method="get" action="<?php echo home_url(); ?>" role="search" tabindex="0">

                    </div>

                  <!-- [END] .navbar-collapse -->
               </div>
               <!-- [END] .container-fluid -->
            </nav>

container-fluid image我有div类，container-fluid，我检查了container-fluid中的所有元素，尽管div和{{ 1}}类的身高更高。

我也附了一张照片。我尝试过container-fluid无效。

max-height, min-height height
