无论我怎么尝试，我都无法使这个HTML页面滚动。
谁能帮忙？
我试过删除所有overflow:hidden. 我尝试在class中添加overflow:scroll和auto.
这是我的代码：
.banner {
text-align: center;
position: relative;
background-color: cyan;
width: 100%;
height: 140px;
z-index: -1;
line-height: 10px;
margin: 0px, 0px;
overflow-y: auto;
}
.banner h1 {
font-size: 60px;
color: blue;
}
.infobar {
border: 2px solid red;
top: 200px;
left: 0.5%;
height: 250px;
width: 99%;
position: relative;
}
.banner h2 {}
.banner h3 {}
.intro h1 {}
.intro p {}
.meme {
color: black;
width: 100%;
}
.meme table {
width: 98%;
}
/* If you want the top function to work the position must be set to fixed of a div*/
.meme#table1 {
top: 240px;
position: static;
overflow: scroll;
}
.meme h1 {
font-size: 20px;
width: 100%;
height: 20px;
background-color: red;
border: red solid;
border-width: 0px 5px 0px 5px;
}
.meme img {
border-style: solid;
border-width: 5px;
border-color: red;
width: 100%;
height: auto;
}
.meme tr {
border-spacing: 0px;
}
body {
background: url("http://wolvoman80.co.uk/wp-content/uploads/2016/11/Theresa-May.jpg") no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
.navigationbar {
text-align: center;
position: fixed;
background-color: rgba(255, 6, 6, 0.5);
width: 100%;
height: 80px;
z-index: -1;
top: 145px;
margin: 0px, 0px;
}
.navigationbar a {
font-size: 60px;
padding-right: 0.5em;
color: blue;
overflow: hidden;

</html>不完全知道您要滚动哪个 DIV，但是，如果它是带有类.banner的div，那么只需将z-index更改为 0
.banner {
text-align: center;
position: relative;
background-color: cyan;
width: 100%;
height: 140px;
z-index: 0; // Negative indexes put the element behind other elements and wont let you control it by mouse events
line-height: 10px;
margin: 0px 0px;
overflow-y: scroll;
}
CSS：
body{
height:100%;
}
因为和其他人一样，我不知道你想滚动什么。
