一、浮动
left 元素向左浮动
right 元素向右浮动
none 元素不浮动
inherit 从父级继承浮动属性
#fd{ width: 100px; height: 100px; background-color: red; float: left; } #sd{ width: 100px; height: 100px; background-color: blue; float: left; } #td{ width: 100px; height: 100px; background-color: green; float: left; } #container{ width: 400px; height: 500px; background-color: darkgray; }
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>浮动</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <div id="container"> <div id="fd"></div> <div id="sd"></div> <div id="td"></div> </div> </body> </html>
二、clear属性
去掉浮动属性(包括继承来的属性)
left、right 去掉元素向左、向右浮动
both 左右两侧均去掉浮动
inherit 从父级继承来clear的值
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>浮动</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <div id="container"> <div id="fd"></div> <div id="sd"></div> <div id="td"></div> <div id="text">HelloWorld!</div> </div> </body> </html>
#fd{ width: 100px; height: 100px; background-color: red; float: left; } #sd{ width: 100px; height: 100px; background-color: blue; float: left; } #td{ width: 100px; height: 100px; background-color: green; float: left; } #container{ width: 280px; height: 500px; background-color: darkgray; } #text{ clear: left; }
