well wrodpress.com can’t handle plugins.
to display sourcecode i use the unsorted list container like this:
<ul style=”margin-left:0;border:1px solid #D8D8D8;background-color:#F8F8F8 ;overflow:auto;width:100%”><pre>
main(){
}
public veryLongFunctionWithoutAnyPurposeJustToShowTheOverFlowEffect(){
}
</pre></ul>
it will look like this:
main(){
}
public veryLongFunctionWithoutAnyPurposeJustToShowTheOverFlowEffectNeedSomeMoreWidth(){
}
in ie7 it seems that the pre is too large for the ul container in height. but pre has only the width attribute 
Is it really work?
