<div class="navigation-menu w-32 d-flex flex-row">
   <div class="visible"><a href="#">??????1</a></div>
   <div class="visible"><a href="#">??????1</a></div>
   <div class="visible"><a href="#">??????1</a></div>
   <div class="visible"><a href="#">??????1</a></div>
   <div class="visible"><a href="#">??????1</a></div>
   <div id="more-hd more-vis"><i class="fas fa-chevron-circle-down"></i></div>  
 </div>

我试图隐藏最后一个Div.I使用bootstrap.So,d-none没有帮助,在css中#more-hd display:none也是如此,也是JS document.getElementById("more-hd").style.display = "none".它总是可见的..我也尝试过ul> li首先......没有任何反应
