1.position:relative
相较于正常位置的定位
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> #div1{ width: 150px; height: 150px; background-color: red; } #div2{ width: 150px; height: 150px; background-color: yellow; position: relative; left: 50px;//第二个div块离左边窗口50px top: 10px;//div2块相对于上面的div1块有
10px
}
</style>
</head>
<body>
<div id="div1">woshidiv1</div>
<div id="div2">woshidiv2</div>
</body>
</html>
下图为代码结果：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> #div1{ width: 150px; height: 150px; background-color: red; } #div2{ width: 150px; height: 150px; background-color: yellow; position: relative; left: 150px; top: -150px; } </style> </head> <body> <div id="div1">woshidiv1</div> <div id="div2">woshidiv2</div> </body> </html>

2.position:absolute若滚动浏览器，则区块随之滚动
相对于浏览器窗口的左上角
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<style>
#div1{
width: 150px;
height: 150px;
background-color: red;
}
#div2{
width: 150px;
height: 150px;
background-color: yellow;
position: absolute;
left: 160px;//距离窗口左边160px
top: 150px;//距离窗口上边150px
}
</style>
</head>
<body>
<div id="div1">woshidiv1</div>
<div id="div2">woshidiv2</div>
</body>
</html>

3.position:fixed位移基于浏览器左上角，以这种方式定位，若滚动窗口这个区块不随之滚动
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> #div1{ width: 150px; height: 150px; background-color: red; } #div2{ width: 150px; height: 150px; background-color: yellow; position: fixed; left: 160px; top: 150px; } p{ font-size: 50px; } </style> </head> <body> <div id="div1">woshidiv1</div> <div id="div2">woshidiv2</div> <p>带我飞积极发挥好长度均带我飞积极发挥好长度均带 带我飞积极发挥好长度均带我飞积极发挥 带我飞积极发挥好长度均带我飞积极发挥好长度均 带我飞积极发挥好长度均带我飞积极发挥好长度均 带我飞积极发挥好长度均带我飞积极发挥好长度均带我飞积极发挥好长度均带我飞积极发

4.position:static表示默认值
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> <style> #div1{ width: 150px; height: 150px; background-color: red; } #div2{ width: 150px; height: 150px; background-color: yellow; position: static; } </style> </head> <body> <div id="div1">woshidiv1</div> <div id="div2">woshidiv2</div> </body> </html>
下图为代码结果：
5.position:auto由浏览器自己计算
