<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>css三栏布局之float left与 相对width</title> <style> .block1,.block2,.block3{ float:left; width:32%; height:50px; border:1px dashed #F00; margin:2px; } .block1{ background-color:red;} .block2{background-color:blue;} .block3{background-color:#ffe6b8;} </style> </head> <body> <p class="block1">block1</p> <p class="block2">block2</p> <p class="block3">block3</p> </body> </html>
2.绝对定位,通过absolute 定位使其脱离文档流,可以自适应定义三栏宽度
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>三栏布局css之绝对定位</title> <style> .left,.right{width: 200px;height: 200px; position: absolute;} .left{left:10px;background-color: red;} .right{right:10px;background-color: blue;} .center{margin:2px 210px ;background-color: yellow;height: 200px; } </style> </head> <body> <p class= "left">left</p> <p class = "right">right</p> <p class = "center">center</p> </body> </html>
3.使用自身浮动,float left 和float right
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>三栏布局css之使用自身浮动</title> <style> .left,.right{width: 200px;height: 200px;} .left{float:left;background-color: red;} .right{float:right;background-color: blue;} .center{margin:2px 210px ;background-color: yellow;height: 200px; } </style> </head> <body> <p class= "left">left</p> <p class = "right">right</p> <p class = "center">center</p> </body> </html>
