今天偶来介绍如何在dedecms文章列表加上序号：

css代码部分 
<style type="text/css"> 
<!-- 
.downtop { 
FLOAT: left; OVERFLOW: hidden; WIDTH: 218px; HEIGHT: 278px 
} 
.downtop UL.text { 
MARGIN: 0px 10px; WIDTH: 198px; PADDING-TOP: 5px 
} 
.downtop UL.text LI { 
WIDTH: 198px 
} 
.downtop UL.text SPAN { 
DISPLAY: block; FLOAT: left 
} 
.downtop UL.text SPAN.num { 
MARGIN-TOP: 4px; PADDING-LEFT: 1px; FONT-WEIGHT: bold; FONT-SIZE: 10px; WIDTH: 18px; LINE-HEIGHT: 12px; HEIGHT: 13px; TEXT-ALIGN: center;COLOR: #fff; BACKGROUND-COLOR: #b7b7b7 
} 
.downtop UL.text LI SPAN.active { 
BACKGROUND-COLOR: #7abdff 
} 
.downtop UL.text SPAN.tit { 
PADDING-LEFT: 10px; OVERFLOW: hidden; WIDTH: 168px; WHITE-SPACE: nowrap; HEIGHT: 21px 
} 

--> 
</style> 


dede标签部分代码 
<DIV class="downtop border"> 
<UL class=text> 
{dede:arclist orderby=pubdate type='commend.' titlelen='26' row='10' channel=3} 
<LI>[field:global runphp='yes' name=autoindex] 
$a="<SPAN class='num active'>"; 
$b="</SPAN>"; 
$c="<SPAN class='num'>"; 
if (@me > 3) @me = $c.@me.$b; 
else @me = $a.@me.$b; 
[/field:global] <SPAN class=tit><A /> href="[field:filename/]">[field:title/]</A></SPAN></LI> 
{/dede:arclist} 
</UL> 
</DIV>
