1、什么是响应式 Web 设计?

  • RWD 指的是响应式 Web 设计(Responsive Web Design)
  • RWD 能够以可变尺寸传递网页
  • RWD 对于平板和移动设备是必需的

2、创建自己的响应设计

  举例:

 <!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>My test page</title> <!--float:整体向左浮动/向右浮动-->
<!--margin:边缘,到边缘的距离-->
<!--padding:填充物-->
<!--width:宽度-->
<!--height:高度-->
<!--border:边框-->
<style>
.city {
float: left;
margin: 50px;
padding: 15px;
width: 300px;
height: 300px;
border: 1px solid black;
}
</style>
</head> <body>
<h1>W3School Demo</h1>
<h2>Resize this responsive page!</h2> <div class="city">
<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="city">
<h2>Paris</h2>
<p>Paris is the capital and most populous city of France.</p>
</div> <div class="city">
<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>

  输出结果:略。

3、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">
<title>My test page</title> <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>
<h2>Resize this responsive page!</h2>
</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>

  输出结果:略。
