控制文本的空间

根据Cascading Style Sheet规范，你应当可以控制文本行的高度，字母的空间以及单词的空间。然而非常遗憾，当前版本的Netscape和Microsoft的浏览器只支持行高度的属性。下面的HTML文件说明了这些特性（见图7.25）：

<HTML>

<HEAD>
<TITLE> Style </TITLE>

<STYLE>

<!--

.BigLines {line-height: 200%}

-->

</STYLE>

</HEAD>

<BODY>

<P CLASS=BigLines>

当这个文件在网络浏览器上显示时，第一段中的文本行之间的空间大小为200％（当前字体大小的两倍）。除了使用百分号外，你也可以使用前面所述的任何一个度量单位，如象素或点。
