Question

我真的不想丢失悬停功能，我需要一种不丢失悬停功能的方法。

在纯CSS（无JavaScript）中，如何让下拉菜单关闭下拉菜单外的点击，而不会丢失悬停功能？

以下是使用关闭外部点击功能的JavaScript下拉菜单的用户示例。

这是我的带有悬停和onClick的下拉菜单CSS：

  .acn-menu {
  text-align: center;
  background-color: rgba(0, 0, 0, 0.9);
}

.label_openclose {
  display: none;
}

.menu-tabs {
  height: 100%;
  padding-left: 0;
  padding-right: 0;
  padding-top: 0;
  padding-bottom: 0;
}

/* This CSS makes the Solutions dropdown menu push
   down the other two items when in mobile view. */
@media (min-width: 320px) {
  .menu-tabs {
  position: absolute;
  }
}

.menu-tabs .elem {
  box-sizing: border-box;
  padding: 0 20px;
  float: left;
  height: 100%;
  line-height: 70px;
  background-color: rgb(30, 30, 30);
  color: white;
}

.menu-check {
  display: none;
}


label {
  margin-bottom: 0;
}

.label_openclose {
  display: inline-block;
  width: 60px;
  min-height: 50px;
  background-color: transparent;
  cursor: pointer;
  overflow:hidden;
  display:block;
}

.menu-tabs .elem {
  line-height: initial;
  float: initial;
  height: 0px;
  cursor: pointer;
  border-top: 0px solid #000;
  overflow: hidden;
}

.menu-check:checked~.menu-tabs .elem {
  height: 25px;
  color: white;
  border-top: 2px solid rgba(255, 255, 255, 0.2);
}

.label_openclose:hover~.menu-tabs .elem {
  border-top: 2px solid rgba(255, 255, 255, 0.2);
  height: 25px;
}
 .label_openclose~.menu-tabs:hover .elem {
  border-top: 2px solid rgba(255, 255, 255, 0.2);
  height: 25px;
}

我可以在不使用JS的情况下获得近距离点击吗？这是一个小提琴：https://jsfiddle.net/Ld5L2tnf/

display:block;
background-color:blue;
text-align:center;

border:0px;
outline:none;
line-height:0;

.blackout{ /*This Div covers the page with the labelBlackout Label in it. nothing can be clicked unless The Label inside clicked first triggering the checkbox. */
width:100%;
height:100%;
float:left;
position:fixed;
z-index:15; 
background-color:transparent; /*    You can add a background color like this. background-color:black; opacity:0.7;*/
display:none;
}  
.labelBlackout{ /*the Label inside the blackout div that covers the page*/
width:100%;
height:100%;

margin-top:5px;
}
input[type=checkbox].gone:checked ~ div.blackout{display:block;}  
input[type=checkbox].gone:checked ~ label.mycheckDrop{display:block;}    
.buttoncomtainer1:hover > .mycheckDrop{display:block;}
