如何在materialize.css中删除可折叠div/li的边框

Question

我正尝试在集合列表项中创建可折叠的div/li。但我不希望可折叠div的灰色边框可见。

标记：

<li class="collection-item"> 
    <ul class="collapsible" data-collapsible="accordion"> 
     <li> 
      <div class="collapsible-header">First</div> 
      <div class="collapsible-body">Lorem ipsum dolor sit amet.</div> 
     </li> 
    </ul> 
</li> 

的CSS：

.collapsible-header, .collapsible-body, .collapsible, ul.collapsible>li 
{ 
    margin-left: 0px; 
    margin-right: 0px; 
    margin-top: 0px; 
    margin-bottom: 0px; 
    padding: 0rem !important; 
    border-top: 0px!important; 
    border-right: 0px!important; 
    border-left: 0px!important; 
    border-bottom: 0px!important; 
    box-shadow: 0px; 
    background: #fff; 
} 

Answer 1

使用这个CSS box-shadow: none!important;

.collapsible-header, .collapsible-body, .collapsible, ul.collapsible>li 
 
{ 
 
    margin: 0!important;; 
 
    padding: 0!important; 
 
    border: 0!important; 
 
    box-shadow: none!important; 
 
    background: #fff; 
 
}
