下拉菜单问题（位置）

标签： html css drop-down-menu position css-position

我需要有关下拉菜单的帮助。当我将鼠标悬停在带有隐藏下拉菜单的选项卡顶部时，我遇到了这个问题。我遵循了W3Schools的说明

W3Schools的说明要求我使用position: absolute，但如果我这样做而不是position: relative，则下拉菜单甚至无法打开。

在HTML中，将两个菜单项都包装在<div class="dropdown">。

中

在CSS中，在悬停时添加position: absolute。 

.dropdown {
  float: left;
  overflow: hidden;
}

.dropdown .projects {
  color: #fff39e;
  border: none;
  background-color: #f9fae8;
  font-size: 18px;
  padding: 12px;
  text-decoration: none;
  font-family: 'Lato', sans-serif, Helvetica;
  font-weight: 900;
  line-height: 25px;
  margin: 0;
}

.dropdown-projects {
  display: none;
  position: relative;
  color: #f9fae8;
  background-color: #101119;
  min-width: 160px;
  z-index: 2;
}

.dropdown-projects a {
  float: none;
  color: #f9fae8;
  padding: 10px;
  text-decoration: none;
  display: block;
  text-align: left;
  font-size: 16px;
  font-family: 'Lato', sans-serif, Helvetica;
  font-weight: 400;
  line-height: 0.6;
  margin: 0;
}

.dropdown-projects a:hover {
  color: #fff39e !important;
}

.dropdown:hover .dropdown-projects {
  display: block;
  /* added */
  position: absolute;
}

.dropdown .dilettante {
  color: #caf5ce;
  border: none;
  background-color: #f9fae8;
  font-size: 18px;
  padding: 12px;
  text-decoration: none;
  font-family: 'Lato', sans-serif, Helvetica;
  font-weight: 900;
  line-height: 25px;
  margin: 0;
}

.dropdown-dilettante {
  display: none;
  position: relative;
  color: #f9fae8;
  background-color: #101119;
  min-width: 160px;
  z-index: 2;
}

.dropdown-dilettante a {
  float: none;
  color: #f9fae8;
  padding: 10px;
  text-decoration: none;
  display: block;
  text-align: left;
  font-size: 16px;
  font-family: 'Lato', sans-serif, Helvetica;
  font-weight: 400;
  line-height: 0.6;
  margin: 0;
}

.dropdown-dilettante a:hover {
  color: #caf5ce !important;

.dropdown:hover .dropdown-dilettante {
  display: block;

<div class="dropdown">
  <button class="projects">PROJECTS</button>

答案 1 :(得分：0)

在您的下拉列表中使用absolute position并使用以下代码进行显示

.projects:hover + div.dropdown-projects {
   display: block;
}

.dilettante:hover + div.dropdown-dilettante {
   display: block;
}

这是working file

你的代码也需要很多其他改进。

您必须相应地编辑CSS

＆＃13;
＆＃13; 
.navbar {
  overflow: hidden;
  background-color: #fff;
  /* Chnage the Background */
  padding: 10px;
  font-size: 16px;
  font-family: 'Lato', sans-serif, Helvetica;
  line-height: 0.6;
}

.navbar a {
  float: left;
  font-size: 16px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.dropdown {
  float: left;
  overflow: hidden;
}

.dropdown .dropbtn {
  font-size: 16px;
  border: none;
  outline: none;
  color: #FFF39E;
  padding: 14px 16px;
  background-color: inherit;
  font-family: inherit;
  font-weight: 900;
  margin: 0;
}
