即使有正确的缩进,这些嵌套的 div 仍然让人觉得非常混乱。在 HTML 5 中,可以将这些元素替换为语义性的元素,见代码2 用 HTML5编写的典型blog页面
以下是代码片段:[www.xlnv.net] <html>

It started out as a nice winter morning when we arrived at the site at 7:30 A.M., progressed to Spring around 10:00 A.M., and reached early summer by 10:15. </p> </article> <article> <h2><a href= "/blog/birding/2007/04/23/but-does-it-count-for-your-life-list/"> But does it count for your life list?</a></h2> <p>Seems you can now go <a href="http://www.wired.com/science/discoveries/news/ 2007/04/cone_sf">bird watching via the Internet</a>. I haven't been able to test it out yet (20 user limit apparently) but this is certainly cool. Personally, I can't imagine it replacing actually being out in the field by any small amount. On the other hand, I've always found it quite sad to meet senior birders who are no longer able to hold binoculars steady or get to the park. I can imagine this might be of some interest to them. At least one elderly birder did a big year on TV, after he could no longer get out so much. This certainly tops that.</p> </article> <nav> <a href="/blog/page/2/">« Previous Entries</a> </nav> </section> <nav> <ul> <li><h2>Info</h2> <ul> <li><a href="/blog/comment-policy/">Comment Policy</a></li> <li><a href="/blog/todo-list/">Todo List</a></li> </ul></li> <li><h2>Archives</h2> <ul> <li><a href='/blog/2007/04/'>April 2007</a></li> <li><a href='/blog/2007/03/'>March 2007</a></li> <li><a href='/blog/2007/02/'>February 2007</a></li> <li><a href='/blog/2007/01/'>January 2007</a></li> </ul> </li> </ul> </nav> <footer> <p>Copyright 2007 Elliotte Rusty Harold</p> </footer> </body> </html> |
现在不再需要 div 了。不再需要自己设置 class 属性,从标准的元素名就可以推断出各个部分的意义。这对于音频浏览器、手机浏览器和其他非标准浏览器尤其重要。
