javascript - 如何将悬停叠加到 flex 容器中的 flex 元素

Question

这是我的代码。我想将灰色覆盖在每个 flexItem 的内容上。该层也必须位于图像上方。我找不到解决方案，有人知道吗？

我尝试在 flexCont 上使用相对位置，在 flexItem 叠加层上使用绝对位置，但无能为力。

我在 js 中有一个函数，它在悬停时应用一个覆盖类，如果你不再悬停，则将其删除

$('.flexItem').hover(
        function() {
            $(this).addClass( 'overlay' );
            console.log('hover')
          }, function() {
          $(this).removeClass( 'overlay' ); 
            console.log('no hover')
          }
    );

.flexCont{
    display: flex;
    display: -ms-flex;
	display: -webkit-flex;
    flex-direction: row;
}

.flexContO{
    display: flex;
    display: -ms-flex;
	display: -webkit-flex;
    flex-direction: row;
}

.flexContO>div{
    width:50%;
}

.flexCont .flexItem{
    flex: 1 1 25%;
}

.flexItem{
    display: flex;
    flex-direction: column;
}
.overlay{
    background-color: rgba(0,0,0,0.5); /*dim the background*/
    position: relative;
z-index:999!important;
  }

.flexItemV{
    display: flex;
    flex-direction: column;
    justify-content: space-between;
}
.flexItemO{
    display: flex;
    flex-direction: row;  
}
.flexItemO>div{
    width:50%;
}

.flexItem1{
   height:375px;
   justify-content: center;
   align-items: center;
   display: flex;
   flex-direction: column;
   text-align:center;
   padding:20px;
}

.flexItem2>img{
    width: 100%;z-index:99!important;
}

.flexItemV1{

}
.flexItemV2{
    
}

您可以使用以下更新的代码:

$('.flexItem').hover(
  function() {
    $(this).addClass( 'overlay' );
    $(this).find('img').css('opacity', '0.6');
    //console.log('hover')
  }, function() {
    $(this).removeClass( 'overlay' ); 
    $(this).find('img').css('opacity', '1');
    //console.log('no hover')
  }
);

.flexCont{
    display: flex;
    display: -ms-flex;
	  display: -webkit-flex;
    flex-direction: row;
}

.flexContO{
    display: flex;
    display: -ms-flex;
	  display: -webkit-flex;
    flex-direction: row;
}

.flexContO>div{
    width:50%;
}

.flexCont .flexItem{
    flex: 1 1 25%;
}

.flexItem{
    display: flex;
    flex-direction: column;
}
.overlay{
    background-color: rgba(0,0,0,0.5); /*dim the background*/
    position: relative;
    z-index:999!important;
}

.flexItemV{
    display: flex;
    flex-direction: column;
    justify-content: space-between;
}
.flexItemO{
    display: flex;
    flex-direction: row;  
}
.flexItemO>div{
    width:50%;
}

.flexItem1{
   height:375px;
   justify-content: center;
   align-items: center;
   display: flex;
   flex-direction: column;
   text-align:center;
   padding:20px;
}

.flexItem2>img{
    width: 100%;
    z-index:99!important;
}
