第一种方法：采用绝对定位
<!DOCTYPE> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style> .one { position: absolute; height: 200px; width: 300px; background-color: blue; } .two { height: 200px; margin-left: 300px; background-color: red; } </style> </head> <body> <div class="one"></div> <div class="two">第一种方法</div> </body> </html>
第二种方法：采用左浮动
<!DOCTYPE> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style> .one { float:left; height: 200px; width: 300px; background-color: blue; } .two { overflow: auto; height: 200px; background-color: red; } </style> </head> <body> <div class="one"></div> <div class="two">第二种方法</div> </body> </html>
第三种方法：采用flex布局（推荐使用）
<!DOCTYPE> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=no" /> <title>Document</title> <style> *{padding: 0;margin: 0;} #oo{ display: flex; flex-wrap: wrap; } .one { float:left; height: 200px; width: 200px; background-color: blue; } .two { background-color: red; flex: 1; } .three{ background-color: pink; flex: 2; } </style> </head> <body> <div id="oo"> <div class="one">1</div> <div class="two">2</div> <div class="three">3</div> </div> </body> </html>
