<P>和一般的CSS語法不同(參見<A href="005_CSS_Syntax.html">CSS語法</A>)，CSS偽類的語法有兩種。</P><P>第一種：</P><PRE>selector:pseudo-class {property: value} </PRE><P>例句：</P><PRE>a:link {color:red}</PRE><P>第二種：</P><PRE>selector.class:pseudo-class {property: value}</PRE><P>例句：</P><PRE>a.c1:link {color:red}</PRE><H2>錨(a)偽類</H2><P>錨(a)偽類是最常用的偽類。例句如下：</P><PRE>a:link {color: #FF0000} /* 未被訪問的鏈接 紅色 */</PRE><PRE>a:visited {color: #00FF00} /* 已被訪問過的鏈接 綠色 */</PRE><PRE>a:hover {color: #FFCC00} /* 鼠標懸浮在上的鏈接 橙色 */</PRE><PRE>a:active {color: #0000FF} /* 鼠標點中激活鏈接 藍色 */</PRE><P><A href="../css_examples/042_pseudo_class_a.html">演示示例</A></P><P>也可以用HTML的class屬性來設定偽類。例句如下：</P><PRE>a.c1:link {color: #FF0000} /* 未被訪問的鏈接 紅色 */</PRE><PRE>a.c1:visited {color: #00FF00} /* 已被訪問過的鏈接 綠色 */</PRE><PRE>a.c1:hover {color: #FFCC00} /* 鼠標懸浮在上的鏈接 橙色 */</PRE><PRE>a.c1:active {color: #0000FF} /* 鼠標點中激活鏈接 藍色 */</PRE><P><A href="../css_examples/043_pseudo_class_a_class.html">演示示例</A></P><P><STRONG>注</STRONG>：由于CSS優(yōu)先級的關系(后面比前面的優(yōu)先級高)，在寫a的CSS時，一定要按照a:link， a:visited， a:hover， a:actived的順序書寫。 </P><P> </P>
