CSS3为用户添加了三个特殊效果的处理方式：过渡、动画、变化。当用户和界面元素交互时，使用这些特殊样式可大大改善用户的体验效果。这些效果可以直接由浏览器引擎处理，还能节省开销。尽管如此，这些效果会耗费大量的处理能力，尤其是一些复杂的WEB页面上。即使是最基本的效果，也是如此。本篇的目的只是熟悉这三种CSS处理效果，不推荐在实际系统中大篇幅使用。
温馨提示：请谨慎大篇幅使用这些特殊效果。
另外一方面，由于在CCS3标准化之前，主流浏览器都是通过添加厂商前缀方式提供样式支持。所以要解决浏览器兼容问题，使用这些样式，我们不得不为每一个样式添加各个产商前缀，例如添加一个过度延迟时间属性transition-delay，不得不这样写：
</p>
<p class="code">
-webkit-transition-delay: 300ms;<br>
-o-transition-delay: 300ms;<br>
-moz-transition-delay: 300ms;<br>
-ms-transition-delay: 300ms;<br>
transition-delay: 300ms;
</p>

<p>This is a modal window. You can do the following things with it:</p>
<ul>
<li><strong>Read:</strong> modal windows will probably tell you something important so don't forget to read what they say.</li>
<li><strong>Look:</strong> a modal window enjoys a certain kind of attention; just look at it and appreciate its presence.</li>
<li><strong>Close:</strong> click on the button below to close the modal.</li>
</ul>

function toggleDialog(show){

ele = document.getElementById("dialog");
