HTML言语剖析

排版标记

<!--注解--> ; <P> ; <BR> ; <HR> ; <CENTER> ; <PRE> ; <DIV> ; <NOBR> ; <WBR> ; 
■<!--注解-->:                                                                                                                                         ▲Top
 
像很多电脑言语一样,HTML 文件亦提供注解功用。浏览器会忽略此标记中的文字(可以 是很多行)而不作显示,普通使用目的:
为文中不同部份加上说明,方便日后修正。
这对较复杂或非私人网页尤其重要,它不单是提示自已,亦提示你的同事这部分 做什么、那部分做什么。
例子:
<!--由这处开始是产品订购表格-->

用作版权声明。
假如你不希望别人使用或复制你的网页,可加上警告字眼。
例子:
<!--本文版权为 1998, Creation of Webpage 所拥有,未经许,请勿抄摘-->
 
■ <P> :                                                                                                                                                 ▲Top
 
<P>称为段落标记。作用:为字、画、表格等之间留一空白行。
本来<P>是一围堵标记,标于一段落的头尾,但从 HTML 2.0 开始己不需求</P>作结尾。

<P> 的常用参数: 如:<p align="center">

align="center"
可选值:right, left, center。
内定值: align="left"
例子:
原始码
Here is the text for my paragraph. It does't matter how long it is,
how many space are between the words or when I decide to hit the return key.
It will create a new paragraph only when I begin the tag with another one.
<P>Here's the next paragraph.
