<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> html, body { margin: 0; padding: 0; height: 100%; } .if-top { display: block; border: none; width: 100%; height: 120px; } .if-menu { width: 20%; height: 100%; border: none; } .if-content { width: 78%; height: 100%; border: none; } .div-outer { height: 100%; box-sizing: border-box; padding-top: 100px; } .div-top { background-color: burlywood; height: 100px; margin-top: -100px; } .div-content { background-color: #8ddad3; height: 100%; } </style> </head> <body> <div class="div-outer"> <div class="div-top"> 你好 </div> <div class="div-content"> 世界 </div> </div> <!--<iframe class="if-top" src="top.html"></iframe>--> <!--<iframe class="if-menu" src="menu.html"></iframe>--> <!--<iframe class="if-content" src="content.html"></iframe>--> </body> </html>
