HTML Comments

HTML中插入注释用 <!-- I am a comment -->, it will not displayed by the browser. 在debug阶段，可以把相关HTML元素放在开闭箭头之间。

Conditional comments

Conditional comments enable you to add a browser specific code that executes only if the browser is IE but is treated as a comment by other browsers. 条件注释使得元素中的代码只在IE浏览器下运行显示

syntax：

<!--[if IE 8]>This is IE 5<br><![endif]-->

HTML <dfn>

该元素的使用方法有三种情况：

1.如果有 title 属性，则它的title定义这个条款

<p>The <dfn title="World Health Organization">WHO</dfn> was founded in 1948.</p>

2.如果该元素包含一个定义了 title 的 <abbr> 元素，则 <abbr> 的 title 定义这个条款

<p>The <dfn><abbr title="World Health Organization">WHO</abbr></dfn> was founded in 1948.</p>

3.该元素的内容是条款，而它的父元素则包含该条款的定义。

<p>The <dfn>WHO</dfn> World Health Organization was founded in 1948.</p>

<noscript> tag

The <noscript> tag is used to provide an alternate content for users that have disabled scripts in their browser or have a browser that doesn’t support client-side scripting. 该标签旨在当用户浏览器禁止scripts或者浏览器不支持客户端脚本运行时，提供并显示可替换的内容。

The <noscript> element can contain all the elements that you can find inside the <body> element of a normal HTML page. 该元素可以包含所有那些适用于正常HTML页面<body>元素中的元素。

只有在客户端不支持或者禁用了JS的情况下，才会显示该标签里的内容。
