<div> − 提供面向 HTML 內容的通用容器。
<header> − 表示頁首部分。
<footer> − 表示頁尾部分。
<article> − 表示文章。

      </div>
      
      <article class = "w3-container">
         <p>The latest versions of Apple Safari, Google Chrome, Mozilla Firefox, and Opera all support many HTML5 features and Internet Explorer 9.0 will also have support for some HTML5 functionality. The mobile web browsers that come pre-installed on iPhones, iPads, and Android phones all have excellent support for HTML5.</p>
      </article>
      
      <section class = "w3-container">
         <p>HTML5 is designed, as much as possible, to be backward compatible with existing web browsers. New features build on existing features and allow you to provide fallback content for older browsers.</p>

      <footer class = "w3-container w3-red">
