如何将叠加层悬停在flex容器中的flex项目上

问题描述 投票：2回答：5

这是我的代码。我想在每个flexItem的内容上放置灰色覆盖。图层也必须在图像上方。我找不到解决方案，任何人都有一些想法？

我尝试在flexCont上的相对位置，并在flex项目重叠但绝对无关。

我有js中的函数在悬停时应用覆盖类，如果你不悬停更多，则删除它

$('.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{

}
.overlay{

你这里没有任何实际的“叠加”，你只是设置.flexItem元素本身的背景。因此，当然，您设置的背景颜色不会“覆盖”图像，因为图像是元素的内容，而背景则是背面......

您可以简单地使用位于元素其余部分的伪元素：

$('.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;
    position: relative;
}
.overlay::after{
    content: "";
    position: absolute;
    top:0; bottom:0; left:0; right:0;
    background-color: rgba(0,0,0,.5); /*dim the background*/
  }

.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;
}

您需要将叠加层定义为.flexItem中的单独元素

$('.flexItem').hover(
  function() {
    $(this).find('.overlay').show();
  },
  function() {
    $(this).find('.overlay').hide();
  }
);
.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;
  position: relative; /* Added */
}

.overlay {
  background-color: rgba(0, 0, 0, 0.5);
  position: absolute; /* Changed from relative */
  top: 0; /* Added */
  left: 0; /* Added */
  width: 100%; /* Added */
  height: 100%; /* Added */
  display: none; /* Added */
}

.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%;
}

.flexItemV1 {}

.flexItemV2 {}

好的，您可以使用after伪元素来设置此样式。检查一下

$('.flexItem').hover(
  function() {
    $(this).addClass( 'overlay' );
  }, function() {
    $(this).removeClass( 'overlay' ); 
  }
);
.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 {
    /*dim the background*/
    position: relative;
}

.overlay:after {
    content: "";
    background-color: rgba(0, 0, 0, 0.5);
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
