in thread Change default style sheet: add line numbers

This would block C&P without clicking on DOWNLOAD, that's why many would object. But an interactive JS toggle might solve that.

Hmm , firefox doesn't copy/paste line numbers ... so I don't think JS is required 

<ol><li><span title="line 1"><div class='codeblock'><tt class='codetex
+t'>#!/usr/bin/perl --</tt></div></span>
<li><span title="line 2"><div class='codeblock'><tt class='codetext'>u
+se strict;</tt></div></span>
<li><span title="line 3"><div class='codeblock'><tt class='codetext'>u
+se warnings;</tt></div></span>
<li><pre class="code"><span title="line 4"><div class='codeblock'><tt 
+class='codetext'>print "Hello <span class="line-breaker">
<font color="red">+</font></span> world!\n";</tt></div></span></pre></
+ol>
