CSS实例:三列等高布局

(编辑：jimmy 日期: 2024/12/25 浏览：3 次 )

三列等高CSS布局的一个实例，
　　修改国外的一个demo，
　　兼容到了IE5.5 和标准的浏览器OperaFirefoxSafari。
　　不过hack太多，不是很喜欢这样做。
全部代码如下：

<h2>Abstract</h2>

<p>The web is constantly evolving. New and innovative websites are being created     every day, pushing the boundaries of HTML in every direction. HTML 4 has     been around for nearly a decade now, and publishers seeking new techniques to     provide enhanced functionality are being held back by the constraints of     the language and browsers.</p>

<p>To give authors more flexibility and interoperability, and enable  more interactive and exciting websites and applications, HTML 5  introduces and enhances a wide range of features including form  controls, APIs, multimedia, structure, and semantics.</p>

<p>Work on HTML 5, which commenced in 2004, is currently being carried out in     a joint effort between the <a href="http://www.w3.org/html/"><abbr title="W3C HTML Working Group">W3C HTML     WG</abbr></a> and     the <a href="http://www.whatwg.org/"><abbr title="Web Hypertext Application Technology Working Group">WHATWG</abbr></a>.     Many key players are participating in the W3C effort including representatives     from the four major browser vendors: Apple, Mozilla, Opera, and Microsoft;     and a range of other organisations and individuals with many diverse interests     and expertise.</p>

<p>Note that <a href="http://www.w3.org/html/wg/html5/">the     specification</a> is still a <em>work in progress</em> and quite a long     way from completion. As such, it is possible that any feature discussed in     this article may change in the future. This article is intended to provide     a brief introduction to some of the major features as they are in the current     draft.</p>
