我想做一个简单的悬停效果，但是当我悬停在div上时，::AFTER背景色覆盖了文本，但我想让文本放在一切之上，我试着调整锚的z-index，但那没有帮助。
*{
margin: 0;
padding: 0;
text-decoration: none;
list-style: none;
box-sizing: border-box;
}
body{
height: 100vh;
display: flex;
justify-content: center;
align-items: center;
}
.box{
width: 300px;
height: 150px;
background-color: blueviolet;
cursor: pointer;
}
a{
position: relative;
display: flex;
justify-content: center;
align-items: center;
font-size: 20px;
height: 100%;width: 100%;
color: black;
}
a::after{
position: absolute;
content: "";
width: 100%;
height: 100%;
background-color: #000000ad;
left: 0;
top: 0;
z-index: -1;
}
a:hover{
color: white;
}
a:hover::after{
z-index: 1;

</html>你可以用像
这样的span分隔文本来解决这个问题<a href=""><span style="z-index: 100;">Home</span></a>
我认为你只是想改变锚的背景颜色，而悬停锚所以我认为你不需要使用后伪类。你可以像我在代码中展示的那样，通过悬停来改变背景颜色。试试这个。如果我没有理解你的问题，请向我道歉。
