How to control the div to be fixed with css?
You can specify the positioning type of the element through the position attribute.
Fixed positioning (position:fixed): The
element is positioned relative to the browser window. No matter how you move your slider, it will will be fixed at a fixed position relative to the browser window. Also note that its sibling elements will ignore its existence in positioning. The top, bottom, left, and right used at this time are also relative to the browser window.
Description
The position attribute defines the positioning mechanism used to establish the layout of the element. Any element can be positioned, but absolute or fixed elements generate a block-level box, regardless of the type of the element itself. A relatively positioned element is offset from its default position in normal flow.
Example:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<style type="text/css">
h2.pos_abs {
position: fixed;
left: 100px;
top: 120px
}
p{
height: 100px;
background-color: palegoldenrod;
}
p.p2{
margin-top:120px ;
}
</style>
</head>
<body style="height: 1200px;">
<h2 class="pos_abs">这是带有固定定位的标题</h2>
