我试图找到一种方法来获取我目前在我网站主页上的悬停效果，将其放置在我为每个页面设置的背景图像上方互动盒子。
基本上，基于颜色的悬停效果应该影响背景图像的顶部，这不是当前的情况。正如您在框1和3中看到的，每次悬停时，颜色都会发生变化。我希望所有包含图像的盒子都是如此。正如我所知，我无法找到一种方法将悬停效果带到堆栈顶部。
基本上，从下面发布的代码中，我认为我需要
.col-md-4:hover{
background-color: #FFE097;
}
取代我在主页面上设置的框。
这是我的主要CSS：
.col-md-4 {
color:#00A5D1;
height:300px;
border: 1px solid #FF8B6F;
}
.col-md-4:hover{
background-color: #FFE097;
}
.col-md-4 h3 {
position: relative;
top: 40%;
transform: translateY(-50%);
}
/* Basic Structure
-------------------------------------------------------------- */
h3 {
font-size:14px;
text-align:center;
font-family: 'Buernard', Garamond, "Buenard", "EB Garamond",'EB Garamond';
}
这是我主页的HTML：
<style>
h3 {
font-size:36px;
font-style: bold;
text-align:center;
font-family:'Buernard', Garamond, "Buenard", "EB Garamond",'EB Garamond';
}

您可以使用堆叠在div顶部的伪元素创建叠加层。
添加以下CSS：
.col-md-4 {
...
position: relative;
}
.col-md-4:after {
content: '';
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
display: block;
background: #FFE097;
opacity: 0;
}
.col-md-4:hover:after {
opacity: .5;
}
.col-md-4 h3 {
position: relative;
z-index: 1;
...
}
