html - 使用子链接时保持父链接悬停

Question

我在设置下拉菜单时遇到了麻烦。只要我使用子菜单，父链接就需要处于悬停状态。

/* Dropdown Button */

.dropbtn {
  background-color: transparent;
  color: #585558;
  padding: 16px;
  font-size: 1em;
  border: none;
  cursor: pointer;
  font-weight: bold;
}


/* The container <div> - needed to position the dropdown content */

.dropdown {
  position: relative;
  display: inline-block;
}


/* Dropdown Content (Hidden by Default) */

.dropdown-content {
  display: none;
  position: absolute;
  min-width: 160px;
  z-index: 1;
  padding-top: -16px;
}


/* Links inside the dropdown */

.dropdown-content a {
  color: #585558;
  padding: 6px 16px;
  text-decoration: none;
  display: block;
  font-weight: bold;
}

.fb:hover {
  color: #3b5998;
}

.ig:hover {
  color: #fb3958;
}

.sc:hover {
  color: #fffc00;
}


/* Show the dropdown menu on hover */

.dropdown:hover .dropdown-content {
  display: block;
}

.dropbtn:hover>a {
  color: #ef5350;
}

.backslash {
  color: #8e8e8e;
  font-weight: bold;
}

<div class="dropdown">
  <button class="dropbtn">Sociale medier</button>
  <div class="dropdown-content">
    <a class="fb" target="_blank" href="#">Facebook</a>
    <a class="ig" target="_blank" href="#">Instagram</a>
    <a class="sc" target="_blank" href="#">Snapchat</a>
  </div>
</div>

如何在使用子链接时让父链接保持悬停状态？

你只需要添加:hover 状态。

.dropdown:hover .dropbtn {
  background: aqua;
}

  border: none;
  cursor: pointer;
  font-weight: bold;
}


/* The container <div> - needed to position the dropdown content */

.dropdown {
  position: relative;
  display: inline-block;
}
