如何使用滚动条在div中修复一个框?
我这样想:
HTML:
<div id="wrapper">
<div class="main">
<div class="container">
<div class="container2">
<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
</div>
</div>
</div>
</div>
CSS:
#wrapper {
position: relative;
width: 100%;
height: 100%;
color: #a3265e;
font-family: 'GillSans-SemiBold';
}
.main {
border: 1px solid red;
position: relative;
width: 100%;
height: 100%;
margin: 0 auto;
padding-top: 380px;
}
.container {
border: 1px solid green;
position: relative;
/*width: 946px;*/
height: 500px;
margin: 0 auto;
overflow: scroll;
}
.container2 {
height: 1500px;
margin: 0 auto;
}
.test {
width: 500px;
height: 500px;
position: fixed;
left: 50%;
margin-left: -250px;
background: black;
}
但是该框与页面一起进行,不仅仅是在div中。
我在这里做错了什么?有人能给我指路吗?
谢谢你们。

我添加了一个div
,它将容器div
和class='test'
div
包装在同一级别,因此测试div可以是包装器内的绝对值,并始终处于固定状态位置
<div id="wrapper">
<div class="main">
<div class="scroll-container">
<div class="container">
<div class="container2">
</div>
</div>
<div class="test">Fixed inside scroll container</div>
</div>
</div>
</div>
CSS:
#wrapper {
position: relative;
width: 100%;
height: 100%;
color: #a3265e;
font-family: 'GillSans-SemiBold';
}
.main {
border: 1px solid red;
position: relative;
width: 100%;
height: 100%;
margin: 0 auto;
padding-top: 380px;
}
.scroll-container{
position: relative;
height: 500px;
}
.container {
border: 1px solid green;
position: relative;
/*width: 946px;*/
height: 500px;
margin: 0 auto;
overflow: scroll;
}
.container2 {
height: 1500px;
margin: 0 auto;
}
.test {
width: 500px;
height: 200px;
color: white;
position: absolute;
top:0;
left: 50%;
margin-left: -250px;
background: black;
z-index: 1;
}

您无法使用position: fixed
执行该操作,因为它始终与视口绑定。你希望它固定在它的上下文中。
