在 child 链接显示时突出显示 parent 导航项

Question

所以，我正在研究导航，它看起来像：

#head .nav {
    position: relative;
    z-index: 1;
}
#head .nav img {
    float: left;
    height: auto;
    padding: 40px;
    width: 200px;
}
#head .nav ul {
    font-family: 'Roboto', sans-serif;
    font-size: 16px;
    padding-right: 20px;
    text-align: center;
    text-transform: uppercase;
    transition: all 0.5s ease;
}
#head .nav li {
    display: inline-block;
    padding: 70px 0 20px;
    position: relative;
}
#head .nav > ul > li > a {
    color: #fff;
    padding: 0 20px 10px;
}
#head .nav > ul > li > a:hover,
#head .nav > ul > li.current_page_ancestor > a {
    border-bottom: 1px solid rgba(255, 231, 208, 0.5);
}
#head .nav li a {
    text-decoration: none;
}
#head .nav li.current_page_item a {
    border-bottom: 1px solid rgba(255, 231, 208, 0.5);
    color: #ffe7d0;
}
#head .nav ul.children li {
    padding: 0;
}
#head .nav ul.children li a {
    background: rgba(255, 255, 255, 0.9);
    color: #191a22;
    display: block;
    margin-bottom: 1px;
    padding: 20px 20px 18px;
    position: relative;
    z-index: 1;
    text-align: center;
    width: 100px;
}
#head .nav ul.children li a:hover {
    background: #fff;
}
#head .nav ul li ul {
    display: none;
    left: -50%;
    margin-top: 20px;
    padding: 0 0 0 10px;
    position: absolute;
    width: 100px;
}
#head .nav ul li:hover > ul,
#head .nav ul li ul:hover,
#head .nav ul li ul:focus {
    display: block;
}

<div class="nav">
    <a href=""><img src="https://url.com/images/logo.png" title="" alt=""></a>
    <ul>
        <li class="page_item page-item-7 current_page_item"><a href="https://url.com/" aria-current="page">Home</a></li>
        <li class="page_item page-item-9"><a href="https://url.com/about/">About</a></li>
        <li class="page_item page-item-11"><a href="https://url.com/media/">Media</a></li>
        <li class="page_item page-item-13"><a href="https://url.com/music/">Music</a></li>
        <li class="page_item page-item-15"><a href="https://url.com/shows/">Shows</a></li>
        <li class="page_item page-item-23 page_item_has_children"><a href="https://url.com/shop/">Shop</a>
            <ul class="children">
                <li class="page_item page-item-24"><a href="https://url.com/shop/cart/">Cart</a></li>
                <li class="page_item page-item-25"><a href="https://url.com/shop/checkout/">Checkout</a></li>
                <li class="page_item page-item-26"><a href="https://url.com/shop/my-account/">My account</a></li>
            </ul>
        </li>
        <li class="page_item page-item-20"><a href="https://url.com/contact/">Contact</a></li>
    </ul>
</div>

我想做的是在显示 child 菜单时突出显示 parent...像这样：

我在想这里可能需要一些 JS，我试过了：

#head .nav > ul > li.page_item_has_children > a {
    border-bottom: 1px solid rgba(255, 231, 208, 0.5);
}

就是一直把border-bottom放在显示link上，不管child ul是否显示，有没有办法添加border-bottom 仅当显示 #head .nav ul.children li a 时？

谢谢，

试试这个。

$(document).ready(function() {
  $('.dropdown').click(function() {
    $('.dropbtn').removeClass('dropbtn-active');
    $(this).find('.dropbtn').addClass('dropbtn-active')
  });

})

ul {
  list-style-type: none;
  padding-left: 1px;
}
.dropdown {
  float: left;
  padding-right: 1px;
}
.dropbtn {
  height: 30px;
}
li a,
.dropbtn {
  display: inline-block;
  color: white;
  text-align: center;
  margin:10px;
  padding:10px;
}
.dropbtn-active {
  background-color: #31b0d5;
  font-weight: bold;
  color:black;
  cursor:pointer;
}
li ,
.dropdown:hover .dropbtn {
  background-color: #31b0d5;
}
.dropbtn:hover{
 color:black;
cursor:pointer;
}

.dropdown a{
text-decoration:none;
}

.dropdown a:hover{
text-decoration:underline;
}

.dropdown:active .dropbtn {
  background-color: #31b0d5;
}
a.dropdown {
  display: inline-block;
}
.dropdown-content {
  display: none;
  position: absolute;
  background-color: #e8f3f4;
  min-width: 100%;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.1);
  z-index: 10;
}

.dropdown-content a {
  color: black;
  padding: 5px 10px;
  display: block;
  text-align: left;
}
.dropdown-content a:hover {
  background-color: #d8dee2
}
.dropdown-content a:visited .dropbtn {
  background-color: #e8f3f4;
}
.dropdown:hover .dropdown-content {
  display: block;
}

我重新开始，终于让一切正常，不需要 JS！

代码没有改变，这里是更新 CSS:

#head .nav {
    position: relative;
    z-index: 1;
}
#head .nav img {
    height: auto;
    padding: 40px;
    position: absolute;
    width: 200px;
    z-index: 1;
}
#head .nav ul {
    font-family: 'Roboto', sans-serif;
    font-size: 0;
    letter-spacing: 1px;
    text-align: center;
    text-transform: uppercase;
}
#head .nav li {
    color: #fff;
    display: inline-block;
    font-size: 16px;
    position: relative;
    text-decoration: none;
}
#head .nav > ul {
    padding-top: 50px;
}
#head .nav > ul > li > a {
    border-bottom: 1px solid transparent;
    display: inline-block;
    padding: 20px 20px 10px;
}
#head .nav > ul > li:hover > a,
#head .nav > ul > li.current_page_item > a,
#head .nav > ul > li.current_page_ancestor > a {
    border-bottom: 1px solid #ccc;
    color: #ccc;
}
#head .nav li a {
    color: #fff;
    text-decoration: none;
}
#head .nav ul li ul {
    border-top: 20px solid transparent;
    display: none;
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
    width: 200px;
}
#head .nav ul li:hover ul,
#head .nav ul li ul:hover,
#head .nav ul li ul:focus {
    display: block;
}
#head .nav ul li ul li {
    width: 100%;
}
#head .nav ul li ul li a {
    background: rgba(255, 255, 255, 0.9);
    color: #5d6896;
    box-sizing: border-box;
    display: block;
    margin-bottom: 1px;
    padding: 20px 20px 18px;
    
}
#head .nav ul li ul li a:hover {
    background: #fff;
    color: #191a22;
}

真正解决我问题的那个：

#head .nav > ul > li:hover > a

现在效果好多了，我喜欢它的结果，希望这对其他人有帮助！
