%26lt;FONT%26gt; %26lt;BASEFONT%26gt; ■实体标记与逻辑标记 ▲Top这一节你必须先明白实体标记与逻辑标记的分别，否则你会迷惑于为何不同 的标记却有相同的效果。两者分别有以下两处

实体标记有固定的显示效果，逻辑标记则依不同浏览器而不同。
例如逻辑标记的 %26lt;EM%26gt; 由于浏览器的不同它所标示的文字不一定出现斜体效果， 它可能是加底线、粗体或反白等，所以这一节是以它们在 IE 和 NC 中的效果作介 绍。
多个实体标记亦可有效标示同一字句，逻辑标记则通常于旧浏览器不能有效显示多 重的标示。
例如两个逻辑标记 %26lt;EM%26gt; 及 %26lt;STRONG%26gt; 同时标示一字句于旧浏览器常失去作用。

实体标记有
%26lt;I%26gt; %26lt;B%26gt; %26lt;U%26gt; 逻辑标记有
%26lt;STRONG%26gt; %26lt;EM%26gt; %26lt;VAR%26gt; %26lt;CITE%26gt; %26lt;DFN%26gt; %26lt;ADDRESS%26gt; %26lt;CODE%26gt; %26lt;KBO%26gt; %26lt;SAMP%26gt; %26lt;TT%26gt;

若要求真确的效果当然以实体标记为佳。

■%26lt;STRONG%26gt; %26lt;B%26gt; ▲Top两者皆能产生字体加粗的效果，但必须注重的是当文件被设为 gb2312 Encoding 时，两者所 标示的中文字不会于 Netscape Netvigator 显示粗体效果。

■%26lt;FONT%26gt; %26lt;BASEFONT%26gt;▲Top这一节只有这两个标记具参数设定，且两者的参数设定是一样的，都是负责设定文字的大 小、字形及颜色，但各有用处，且看以下比较 %26lt;BASEFONT%26gt; 可以用于文件的开头部分，即 %26lt;HEAD%26gt; 与 %26lt;/HEAD%26gt; 之间的位置，将 影响全文字句，是一个空标记，用以改变字体显示的内定值。
%26lt;FONT%26gt; 是应用于文件的内文部分，即 %26lt;BODY%26gt; 与 %26lt;/BODY%26gt; 之间的位置，只影响 所标示的字句，是一个围堵标记。 两标记可同时存在，唯没被 %26lt;FONT%26gt; 所标示的字句才直接受 %26lt;BASEFONT%26gt; 所影 响，而 %26lt;FONT%26gt; 本身亦受 %26lt;BASEFONT%26gt; 的影响。

%26lt;FONT%26gt;的参数设定
例子 %26lt;font face="Arial" size="+2" color="#008000"%26gt;Creation of Webpage%26lt;/font%26gt;

face="Arial"
设定文字的字形。Arial 是常用的一种，请不要使用 Window 内建字 形以外的字形。于没有设定为 Gb2312 Encoding 的中文网页，Netscape Netvigator 不会显示此标记 所指明的任何中文字形。 size="+2"
设定文字的大小。其值可以是绝对或相对，
绝对的意思便是标记自己决定文字的大小，不受 %26lt;BASEFONT%26gt; 的影响，如
size="5" 表示其大小便是 5， 而html内定值为 3，即 size="3"和没有设定是一样的。
相对的意思便是在内定值 3 的基础上增加或减少大小级数，如 size="+2" 便等同绝 对表示法的 size="5"，但若已设定 %26lt;BASEFONT size="n"%26gt; 则其实际大小便是 n+2 不 再是 3+2 了。%26lt;BASEFONT%26gt;只有绝对表示法。 color="#008000"
设定文字的颜色。#008000 表示绿色

例子 原始码%26lt;font size="+1"%26gt;I love Creation of Webpage%26lt;/font%26gt;
%26lt;br%26gt;%26lt;font size="+2" color="#800080"%26gt;I love Creation of Webpage%26lt;/font%26gt;
%26lt;br%26gt;%26lt;font face="Times New Roman" size="5" color="#008000"%26gt;I love Creation of Webpage%26lt;/font%26gt; 显示结果I love Creation of Webpage
