我的按钮目标： - 当用户将鼠标悬停在按钮上时，它会变暗。 - 按钮将链接到与index.html相同的文件夹中的不同html文件
我的代码如下：
body {
background-image: url("res/images/space2.jpg");
}
div.wrapper {
width: 720px;
height: 576px;
margin-left: auto;
margin-right: auto;
}
div.banner {
width: 750px;
height: 160px;
position: relative;
top: 0px;
margin-left: auto;
margin-right: auto;
}
div.topnav {
border-radius: 25px;
background: #03023a;
padding: 20px;
width: 700px;
height: 50px;
position: fixed;
}
.button {
background-color: #050462;
border: none;
color: blue;
padding: 16px 32px;
text-align: center;
text-decoration: none;

font-size: 16px;
margin: 4px 2px;

transition-duration: 0.4s;

}
.button1 {
background-color: #0a07ab;

}
.button1:hover {

}
.button2 {

}
div.maindiv {

height: 97px;

margin-left: auto;

}
div.main {

如上所述，我对HTML缺乏经验并且将我的代码基于在线示例，所以可能存在一些我做过的noob错误。

您的按钮工作正常#mainDiv掩盖了您的#topNav，因此无法将鼠标悬停在按钮上。您可能需要将topnav的z-index设置为1或2，如下所示：
div.topnav{
border-radius:25px;
background:#03023a;
padding:20px;
width:700px;
height:50px;
position:fixed;
z-index:2;
}
这里还有许多其他问题，你可能也想了解一下你的定位，但按钮工作得很好，只是它们被覆盖了。

要让您的:hover州工作，只需向固定z-index添加.topnav值，因为#myDiv覆盖了div.topnav{
border-radius:25px;
background:#03023a;
padding:20px;
width:700px;
height:50px;
position:fixed;
z-index: 1; /*Added*/
}
，需要更高的堆栈索引才能识别你的悬停。
