如果您调整窗口大小，菜单会折叠
菜单折叠时，菜单图标的尺寸较小。
我试图这样做但不幸的是悬停效果被破坏了...悬停图标位于其应有的位置。
这是代码CSS：
.menu-item a img {
border: none;
box-shadow: none;
vertical-align: middle;
width: auto; //here take the picture width
}
@media screen and (max-width: 770px)
{
//here should be writing code for the images to be smaller
}
这是代码HTML：
<nav class="" role="navigation">
<!-- <div class="container-fluid">-->
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="navbar-collapse collapse in" id="bs-navbar-collapse-1">

您可以使用!important;标记修复此问题并调整图标大小，如下所示：
.menu-image-hover-wrapper img.menu-image-title-hide {
width: 20px !important;
height: auto;
margin-left: -20px !important; /* Fix for hover effect . This needs to be the same size as the width */
}
