<!DOCTYPE html> <html> <head> <style> .city { float: left; margin: 5px; padding: 15px; width: 300px; height: 300px; border: 1px solid black; } </style> </head> <body> <h1>W3School Demo</h1> <h2>Resize this responsive page!</h2> <br> <div> <h2>London</h2> <p>London is the capital city of England.</p> <p>It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p> </div> <div> <h2>Paris</h2> <p>Paris is the capital and most populous city of France.</p> </div> <div> <h2>Tokyo</h2> <p>Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.</p> </div> </body> </html>
使用 Bootstrap
另一个创建响应式设计的方法，是使用现成的 CSS 框架。
Bootstrap 是最流行的开发响应式 web 的 HTML, CSS, 和 JS 框架。
Bootstrap 帮助您开发在任何尺寸都外观出众的站点：显示器、笔记本电脑、平板电脑或手机：
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css"> </head> <body> <div class="container"> <div class="jumbotron"> <h1>W3School Demo</h1> <p>Resize this responsive page!</p> </div> </div> <div class="container"> <div class="row"> <div class="col-md-4"> <h2>London</h2> <p>London is the capital city of England.</p> <p>It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p> </div> <div class="col-md-4"> <h2>Paris</h2> <p>Paris is the capital and most populous city of France.</p> </div> <div class="col-md-4"> <h2>Tokyo</h2> <p>Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.</p> </div> </div> </div> </body> </html>
